I've been using GF and the User Registration Addon on Multisite for a while. Most projects are simple 2 sites network to accomodate bilingual sites but...
A few projects are much larger networks including one with 61 sites/blogs. This network is one main org site (artists association) and 50+ artists sites all sharing the same branding as they are under the org's umbrella.
The problem I'm running into is that, some users register to one site (may be the main one or an artist's site) and sometiems want to register to another down the line. But since their email or username is already in use, the User Registration addon rejects the registration. What would be ideal is to give users a notiification that their data is already in use and, do they want to register to the current site too. Is that something possible and/or coming soon?
Thanks and keep on the fantastic work! Didn't have time to beta test 1.6 but can't wait to try it.
