Here is an idea I’ve been pondering on for a while now, how about a community-maintained Google Sheets document? It would make it simple to maintain an Excel-like document among forum members, even allowing stuff like only giving long time members editing access.
The only issue with this idea (and the reason I hadn’t brought it up until now) is that it would require forum members to disclose their GMail accounts, and by proxy, the real name associated with that GMail. There are things that can be done to avoid this, like making new GMail accounts without personal information or making only editors able to view the names of other editors. And this is all without considering the fact that some people simply don’t use GMail and/or aren’t comfortable giving Google their information.
