One concern with the Vanilla software is that it's hard to tell, at a glance, who has been involved. To help address that concern, Chip has added the "in this discussion" plug-in. On the right side of each discussion, you'll see that links to the various forums. Beneath that, there's an alphabetized list of all of the folks who've contributed to that discussion and the date of their last contribution. Clicking on a contributor's name will take you to his/her MFO homepage.
I'd say, "let us know what you think," but I suspect you'd do that even without invitation.
