So, I signed up to four casinos, but the fourth is problematic (I mis-entered my D.O.B. during registration, so can't verify until they update it...which they are taking AGES to do...I will edit this post before 23:59 on 31st if they pull their fingers out :P)
Anyway, the three sign ups that worked:
Rhino
Winomania
Vegasland
Thanks for the competition Hideous, and good luck everyone :)
