I think people themselves know if they are a beginner, but but whatever 'rules' are put in place for this, ultimately its going to be down to individuals to be honest with themselves...
EXACTLY!
Just seeing some of the bluffs, or what others are calling/raising with will help a lot. Also, being advised by the tutors that a pre-flop raise wasn't big enough, or that a post flop call could have been made as the pot odds where there for you to call it etc. Things like that which the beginners hear about but not nessessarily have digested yet.
You explain my reasons for the 'no mucking' rule perfectly! Most have said 'reading is fine, but putting it into practise is the best way of learning.' This wouldn't be set up like the regular Blonde league, but more of a tutoring league. Like I said before and have heard others mention, the

section is great if you're one of those people who can visualise and soak it in from reading the posts. Others need to see it in practise to fully grasp the different concepts. We'd have luxury of both if this works out. At the end of the day, we can put it to a vote if there seems to be split opinion. Nothing is written in stone yet.
