Question about buying in...

[grossmeyer]

Ok, I think everyone on here advocates buying in for the max... I have been doing this, but what about when you drop to say, half or 2/3s a buy-in (for whatever reason... bad beat, I'm playing like a donk, whatever it is), do you add chips back to max? My habit has been not to, because it is easier to track how much I am ahead or behind at any given time.

One other quick question... I play on the .5/.10 full-ring tables (6-max have been very -EV hahaha) for a $10max buy-in, but everyone on here talks about NL25 and NL100 and stuff. What does NL25 etc. mean? My guess is that it is referring to the max buyin which would mean I am playing NL10?
