The CollaborationKit extension will allow people to "join" collaboration hubs (e.g. WikiProjects) at the click of a button. This will help facilitate notifications and generate statistics on member participation. (Users should be able to opt out of being included in metrics reports.)
Design issue: WikiProject Medicine actually wants a fairly complex workflow for memberships. @Isarra will need to figure out how to make membership workflows configurable on-wiki and what the resulting sign-up workflow would look like. This would let us strike a good balance between the moderately complex membership workflow we have with WPX UI and the super-simple workflow originally envisions for CollaborationKit.

Original Report:
A Women in Red user noted that the process for signing up for the WikiProject is too convoluted. There also isn't enough emphasis on the avatar being optional.
@Capt_Swing, might it be possible to appropriate AddMe (or whatever it's called) for WikiProject purposes? It's nice and simple.
