A bit too much SPAM but if you have patience you might see interesting ideas popping up here and there: people that talk about interesting travels others trying to gather people to begin a new one. May be the right group to find a good opportunity.

One of those generic newsgroup where you can find all kind of posts, if you have time and patience enough you might still find something that meet your interests.

It's the main group of the re.travel.* groups. Not so , quite a lot of advertising (but may be sometime it's good to look at!).

It seems a bit more popular than the previous, it has the same amount of advertising but also interesting posts.

A really interesting newsgroup. The meeting place for people going to face a low budget travel with a sack on their back. "In Topic" posts, lively and interesting.

An advertising oriented travel newsgroup... you never know...
