Man, this page was out of date.
I've had a Wikipedia account since the Bush administration, but I haven't been terribly active. Mostly I just make little tweaks and stuff. The only reason I bothered to log back into my old account was to change the way the site looked back to the way I like it.
I did make various small but constructive edits while logged out, of which this remains my favorite.
When I was a child, my mother told me, "If you don't have anything nice to say, don't say anything at all." I think that works well for Wikipedia talk pages, too, except with "constructive with regard to the article at hand" instead of "nice."
