Looks to be a simple, free, hosted message board solution. I don't know what I'd use it for, but it seems like it could come in handy someday. (Anyone want to start a Clipmarks user forum?)

I'm not a fan of these types of forum, but Invision seems to be better than anyone else out there. This free service looks neat but I think the days of these types of forums are numbered.

Shop around. ForumMatrix

Who knew. I always thought you had to pay for hosting and run the software on your own servers.
