I just recently returned from a long absence. (Joined the site in 2009, wrote a few draft SCPs that never got posted because of the mass edit, got distracted by something shiny.) I've recently come back and started writing a few SCPs, and i've done a lot of reading to re-familiarize myself with the terminology we use here.
I realized today that, while we have a few pages that define some of the commonly-used terms, they're scattered about and there's a lot of terms used in many articles that aren't defined. What the wiki could use, in my opinion, is a single glossary, prominently accessible, that provides brief descriptions of the popular terms used in many SCPs, and directs readers to the other pages for more in-depth descriptions of the major ones. If there were interest and a consensus that such a thing would be beneficial, i'd be interested in working on one.
How would people feel about the creation of such a thing? Would anyone be interested in collaborating on such a project?
