So far so good
I've installed RC2 and it seems to working well. I did have a couple of issues right away that were cleared up by simply logging out of everything (Facebook, the site, the admin, etc.) and clearing the browsers cache, cookies and such. After logging back in, it appears to be working. Sometimes I get so busy on so many projects that the simple things hang me up, in this case just clearing the cache is all that was needed. I haven't tried any other the extra modules yet (other than the login and invite modules) but I look forward to experimenting with them. I noticed that my invites are finally making their way back to Facebook again which is nice. Thanks for the great component.
