An enthusiast is basically anyone who is not a pro or semi pro. It in no way connotes a particular level of experience. We have at least one 'Enthusiast' with 30 years experience, while some have just a few months!

The difference between an enthusiast and a semi-pro would be that a semi pro is past the bankroll building stage, playing at a reasonably high buyin/limit and is regularly spending a % of the winnings.

Just PM tetsuo with which one you are, and I'll do it straight away.
