Here's a join link. If it doesn't work, then let me know and I'll add people manually. I just need an email address.

To answer your questions:
- No limit on number of people. It is super-easy to host thousands. Companies just charge this way to make money. The real bandwidth issues and storage issues are negligible.
- No conditions. It's not a big public group, so it doesn't tend to attract trolls or spam. Whoever wants to join, can.
- Go ahead and spread the word. I am grateful.
- It runs off a server on the UCSB campus. All users have access to the data. If anyone wants a dump of it (i.e., a snapshot), I'm happy to assist.
- The data has a mirror. It is also on campus, so if there was a major disaster, we'd lose both copies. But for routine drive failure we're covered.
- No limits on numbers of messages or attachments. Just whatever the software limits are. I'd appreciate it if people didn't try to game that and upload PB data sets. I'm guessing no one will. Movies, images, etc., are fine of course. I'll say something if it becomes an issue at all.
- It's free. I promise to never charge for it. I also promise to never sell any of the data. If there are any concerns about that, I'm happy to put that in writing, if someone wants to draft something up. It's just a bit of community organization I'm happy to do because I'm part of the community and I like to have good resources like this.
