On the Pandora wiki I did a couple little things long ago, nothing really helpful. On the Pyra wiki I think I stuck to adding a US MVNO section, and cleaning up a single page. On Wikipedia various little things related to music, video games stuff (including something insignificant about the Pyra specs, and, SURPRISE!, Game Boy stuff), reverted a few stupid things that were done probably to win a bet (some massive number of catfish species, for example), creating a page about a TV show that me and a handful of people are probably the only ones that care about, added a section about a book to a page, then reverted the reverts that removed it because people claimed it wasn't a "real" book despite it being available since the 70s (some of the books on the page were not known to exist until recently, when they were found in someone's archive, others are self published, and others may not have been seen outside of a small number of people), other little things here and there including fixing spelling and punctuation. I don't often log in on Wikipedia unless it is something I feel is important enough to have my name associated with (as with the book edit war I mentioned). Oh, also some random stuff on wikia, usually related to video games.
