What a mysterious feature. It seems like some users have it displaying all posts they comment in as well as their addon/module uploads, but it's not doing that for me. Might as well see if a blog post at least displays in it.

Update: So it does. That's a relief... or is it?

Update 2: Upon further investigation... Well, for starters, something weird is going on with the tagging system. The website is capable of adding doppleganger tags that group items separately from the originals, and there's no way to remove them or automatically added tags. Moving on, I believe that the tracker is leaving my addons out because they're uploaded through the game, which may not have been the procedure for veteran ToME modders. Jury's still out on how comments work.
