Late to the party, but maybe something easy to do. I like data, and the last upgrade provided a lot more forum statistics than I recall the old system having. I think there may be patterns in the registered user data, for instance, that may shed light on where to spend more effort, etc.
My thought is, after casually reviewing random pages of the registered members pages, that there may be less bang for the buck in creating tools for new users, but more for creating tools for existing members that support the forum. Using amberwolf as an example, although he provided vast knowledge, one of his greatest strengths is how he could utilize the search tool (which isn't the greatest), to provide relevant information to requesters. I've found, to use the search effectively, you have to have enough forum history to search on certain key words and even usernames that we may recall were part of a particular discussion. A greater ability for members to provide support would be a good place to focus. My observation is that at any given time, there may be a dozen or two members that actively support inquiries, besides the admins and mods. There are other active members that are here for the intellectual discussions around different EV issues, but not necessarily providing new user support.
Looking at the member statistics (difficult, since there's not an easy way to access the raw data), I was surprised by how many registered members there are, relative to contributing members. I randomly went through about 50 pages of the stats, and on each page, there were maybe 2 or 3 that have posted a handful of messages. Looking further, those members may have only been active in one or two threads, coming for a quick answer, then never to be seen again. The highest posting number I saw after 50 pages was one member that had 78 messages, but the average per page was more like 2 or 3.
This lines up with what I see day to day, new "members" join so they can post a question and get a quick answer. Maybe one in a dozen actually uses the search tool first, and none read the stickies. I don't think you'll be able to change that behavior. I think the best investment as far as tools go would be toward supporting contributing members rather than trying to create something for folks that join just to solve a singe issue. I'm not an expert in anything, but I know which members on the forum are; experts on the bbshd, or KT controllers, or phase wiring, or throttles, etc., which helps me find the relevant info to support a question and help out in a pinch. If I didn't know their names, it would be hard to search and find the necessary information. I've noticed that I use my draft newbie FAQ all the time to help field questions, so now it's just a tool for me to record and access information I've been able to collect and log from the ES experts.
Anyway, my wish list is to have more data to parse through, since 50 pages out of 2600 pages isn't a good sample size. But only if it's easy to do.
