Please upgrade to 2.2 here.
The 2.0 and 2.1 branches are no longer being updated.
I was very active in this community years ago (can't access that account now because it changed from username to email...) I used the Janine plugin to hack WordPress comments into the forum. Big mistake as it left me unable to upgrade anything.
Today I'm getting the site UNhacked so that I have a separate blog and forum. So, for the first time in nearly four years, I have an upgraded version of Vanilla and I'm a bit lost.
I need to set all the users, except myself, to members, but I can't see any way to do that.
