I think you can still get some use out of GC without paying, I've found some pointers, nothing concrete, concentrations of names etc. There are some good researchers on there - I have to agree on the service side though, shoddy.
Hayho. Rootschat is great, I wouldn't spend so much time here otherwise!! I still use Rootsweb a lot as well. The Cumberland list in particular is fantastic, it isn't so strictly run as others where you get constantly shouted at by Admin!!
