Do you know more projects which publish public dumps? I know Wikimedia, Wikia and Citizendium. Any more? I'm working in a tool for analysing dumps, and I want to add support to all of them.
In my experience, most wikis don't make these available, or only do it infrequently. You can find a one-off copy of the Wikitravel database here (listed at the bottom of the talk page):
http://wikitravel.org/en/Wikitravel_talk:Database_dump
OmegaWiki makes a full, regular dump available (in MySQL format) here:
http://www.omegawiki.org/Development
Note that most of the actual data resides in non-standard tables added by the OmegaWiki software.
I didn't find a dump for WikiHow, but they seem to be the kind of project that would make one available if asked. Finally, I came across this wiki which makes dumps available:
