Hello!
Woodlander, I had no idea that BF was rejecting registrations that used hotmail, that's strange. I registered using my hotmail account and had no issued. You could perhaps email an admin, would be my suggestion, and see if they can't give you a work around, if you can email them at all. Sorry to hear of your troubles registering.
Well, it was many years ago, maybe this is not the case anymore. I'll try again since you had positive experience with your hotmail email.
Thanks a lot for your help!
