Jimmy-
Here's the problem: there's tons of GNU FDL only content in Wikipedia. Anyone can take that content and modify/redistribute it *under the GNU/FDL*. But they can't take the content and modify/redistribute it *under the CC/ATT-SA*, even though the licenses are very similar in spirit.
I'm just looking for a way to get Evan's stuff, not for a way to give him ours :-). Since he has already decided not to use the FDL, he will obviously not be able to use FDL-only content. But if he dual-licenses wikitravel at least we can add useful information from it to the encyclopedia. Otherwise that's not possible without contacting each author.
Regards,
Erik
