are you supposed to be part of the maths society before you join the forums or doesn't it matter. i don't particularly mind (in fact i think it's a good way to reach new people) but if that's not society policy then it's a bit of a hole security-wise.

I believe that you only really need to be a member for the Academic Stuff (revision guides et al), and for voting.

And he said unto them, let there be spam

No, everyone can join the forums and the website does actually differentiate between "society members" and "website members", so it's fine.

P.S. By the way if you want to change your account name to fahdaldapy2002, you can change one of the "a"s (well, not the middle one since that's already taken :P) into an "а" (that looks the same but it's a different character (which means the website will let you use it); it's a cyrillic а (which you can copy and paste if you want to use it)) :P. (My own fahd account has been disabled. :( )
