Maybe I'm using it wrong, but Minki seems pretty technically complicated.  Am I supposed to have to edit using the wiki-code?  That was the problem I had the last time I used a wiki.  People wouldn't format their posts, or they'd format them differently, and it would be hard to look at the site and instantly know what was new, and where the separate ideas were.

Another thing:

Besigner.com looks like a regular blog with multiple people being able to access it. Why not sign up for a Blogger account and set permissions for your friends to all be able to post to it? Again this doesn't include threading, but it will give you pretty much everything you see as Besign.com

It's like a blog, but for one difference, which is what makes it perfect for me: the latest post sorts everything to the top.  This would be like Blogger bumping a blog post to the top again every time someone comments.

Thanks for the other suggestions, I'll take a look.

Google groups is better than I remember it being, but still a bit of a hassle to just invite people to on a whim.
