Another rule that I don't remember being mentioned yet: going south. The term going south (also referred to as ratholing) describes a player winning a pot, leaving the table and buying back in with less chips. So he effectively "secures" his winnings (puts it into his rat hole) and will continue to play only for the minimum. This is commonly considered bad etiquette and most places don't allow this. Online, a common counter measure is to set a time limit. Say you have 1500 chips at a 500 minimum table and leave. During the next hour, if you want to rejoin this table, you have to take at least 1500 chips to the table. After that period you can buy in for the minimum of 500 again. Of course, this doesn't affect other tables, so you can always leave and enter a different table for the minimum if you are not comfortable with your current deep stack.

Oh, and are there waiting lists for full tables? Would be a good idea too.

All of this of course for the future! I think time out and blind posting and showdowns etc. have a higher priority obv.
