Vanilla is no longer sweet.
The forum package Vanilla now has paid advertising links built into the download, according to its developer Mark.
Even though I don't use Vanilla, I think it's a decent program with a great goal. It's not phpbb-ish, but rather has a focus on the topics rather than the forum containers (much like bbPress. I do believe Mark has done a lot of good work on his projects.
Would you believe it? Yet another forum system!
