Email. Such a simple thing.

1) Be polite. Be grateful. Being cranky may make 
people think twice about offering you 
more/bidding if you come off as having a bee in 
your bonnet (so to speak).

2) Answer your email promptly. It could affect 
whether a person will bid or not.

3) Make sure your email (does/has) works(ed) 
consistantly. Animenation's free email has been 
rather sporatic lately. Even my personal 
naraku.com mail has been a touchy spotty. I 
believe Leigh (who's becoming quite famous) was 
having email problems as well. It causes a lot of 
panic and more email for everyone if you post 
saying "AHH! My email's down!" ^_^;;;

That's all I can think of at the moment.
