Tournqment dates and registration

How do I know when the different tournaments start? How do I go
about registering for one?
Thanks to anyone that can answer

any new tourney won't be starting for a while, but when it does you'll
know about it if you keep your eye on the forums - you'll have penty
of notice and there'll be instructions on how to sign up...and you sent
to entry fee to me (joke)
