    Got something to add?

    If you have something to add to the FAQ, send me a PM (not an email, please) here and include the URL of the POST that has the interesting info. Post URLs can be found in the post "number" in the upper right corner of each post in a thread, so find the particular post that has the useful info and get the post URL from the upper right corner of that post. I will eventually add it to the FAQ, although it may take me a whole month! I'm pretty busy

    Want to help? Link to this FAQ in your forum sig!

    It is pretty hard to find this FAQ. There is no link to it in the menu bar(s) at the top of the page (the two FAQ links you see go to ... less useful FAQs). We've asked the admins about improving this, but I guess we're not getting their attention. In the meantime, what helps is if you put a link to this FAQ in your sig. Your "sig" is the customized signature block that appears at the bottom of your comments in a forum thread (e.g. scroll down and see mine below). You can create/edit this block in your account profile here and link to this FAQ. This is also useful for answering common questions, because you can simply reply "see the FAQ in my sig below"

    Background on this FAQ:

    As a service to the community, I have created this FAQ for this forum, with copious links to all of the answers and resources that have been generated in the posts here. You may note that there is already a "FAQ" (linked in the top menubar above) but it really only answers the most basic questions for newbies. There's another "FAQ" (linked in the second menubar above) but that's for the forum engine, e.g. how to manage your profile etc.

    I joined this forum in July 2010 (after the pricing announcement and my own Volt order) and was very active from then through December 2010 when I took delivery on my Volt. During those 6 months I had found that a lot of my activity here was pointing people to other posts that already answered their questions. However I was finding it harder and harder to locate these reference posts, and so I decided to put together this FAQ. I'm much less active here now but I do check in once or twice a month.

    Thanks Chris its a great idea and a generous offer.

    Sometimes when I see new people asking the same thing asked a dozen times before I feel glad because it shows the site is successfully attracting more and more new people. But on the other hand it might get tiring for forum regulars to keep answering the same questions. This will only become more pervasive as the cars roll out and traffic grows.

    FAQ is great idea.

    It may be simpler to put a sticky on those particular threads so that they are easy to find.

    OK, Lyle, I'll get started! Again, I will be editing the post above, and at some point you can move it to a better sub-forum, make it sticky, copy into the static FAQ page, whatever. I'm just going to get going on gathering the data.

    Jason, making those threads sticky isn't a solution because I'm talking about very specific questions ("has anyone seen the installation manual for the Voltec 240V charger?") and those are often buried deep within very, very long threads. For one, lots of great things have been posted in the "Tracking Your Volt Order" thread, but it's now 51 pages long and just pointing someone to that whole thread isn't going to be very helpful. I'm a fan of sticky threads for attracting new users to the most common discussion topics (e.g. order tracking) but in this case it's less useful.

    If you are going to act as Moderator for this new thread it may be good to make a thread/sub-thread for others to post candidate topics for your review for you to add to your thread. I don't know, this may add a flood of duplicates/trivial items and be too big a job for you to review them all. Maybe later after things settle down.

    Lyle -

    I think this is pretty much ready to go. I've been gradually editing it all week and it now has the top posts that I really wanted quick access too. So I guess you can now move this thread someplace more conspicuous, or take a snapshot of it and paste it into the FAQ page on the menubar, or whatever If moving the thread, it's up to you whether to preserve these comments, or just cut them off and lock down this thread. I suppose it would make the most sense in the Newcomers thread, as a sticky thread.

    Wherever this post ends up, I'll continue to tweak it for a couple more weeks -- or longer if I find myself still here after I get my Volt! And I'll link to it in my sig so that people become aware of it.

    I made the thread sticky, so we can leave it right here to direct people to.

    There is a site-wide faq here:

    I think the driver first person video here is a absolute gem and must see.

    Your links are excellent. The need is for an easier way to link to your page. Perhaps a link at the top of the main and forum FAQ pages would be a good start.

    What to call the link?

    You get the idea!

    Mark is right. This is a GREAT page, but it is very hard to find.

    Lyle: can this be posted on the existing "FAQ" page that is listed at the top of every page? I mean the "FAQ" that appears in this bar at the top:
