Best Free Forum Host?

[Cam]

What do you think the best free forum host is?
I am only talking about free forum hosts here, not forum software, website hosts, or paying forum hosts. There's still a lot of free forum hosts though. There's ZetaBoards, ProBoards, Forumotion, FreeForums, and the list goes on.

Why is it the best free forum host?
What is so good about it?
What makes it better than the competition?

Proboards is my favorite free forum host because it's just... simple and easy to use. It doesn't have one of those fancy shmancy admin panels like Forumotion and others do. Proboards allows you to customize your forum anyway you want as long as it abides by their terms.
