First of all, sorry for the late response, I have been busy lately.
Second of all, thanks for the dump.
And here are answers to your questions -
1) Wikipedia DOES provide SQL dumps, and yes- although it's more than 20 GB - look in http://download.wikimedia.org/
2) Never said it's illegal to not provide the SQL dumps. I already mentioned that I was confused, and I know that Ur-Quan wiki is CC-Licensced. I did say that there's nothing illegal in providing the SQL dumps, though. Still, It's a choice of the admin, not obligation.
3) I mentioned other wiki project as an example only. Never said you must do anything because others do it. Don't turn my words into something they're not.
4) In fact, I'm representing only myself. Richard Stallman (The co-founder of GNU) has no connection to me or to what I do. GNU is only my nickname.
5) I wanted the SQL for me only, for curiosity and fun (I want to run my own private wiki server. don't worry - it'll be offline). Since Ur-Quan is a mid-size wiki project, and since I'm a big fan of this game, I thought it is a good option for first try (and I could use the wiki whenever I play, and don't have live internet connection).
Finally , I didn't came to argue, so I really don't understand your negative reaction to me. BTW, if anything I did violeted your robots.txt rules, let me know.
