In no particular order...

1: Leigh Sale of 2002: I would even venture to 
go so far as to say that, for a while after it, the 
cel market fell because everyone was paying 
off their Leigh purchases. I definitely noticed a 
drop...

2. 50% off sales: while I generally don't buy 
from 50% off sales anymore (or when I do, 
what I want is gone), the aftermath of people 
selling to pay for their purchases lets me get 
some lovelies :D

3. Rubberslug: While I really don't like the 
visual "look" of Rubberslug sites, I support 
what is being done as it has opened up the 
community to include many new cel collectors 
who previously would not have had a home; I 
would say RS is at least in some way 
responsible for the current influx of newbies 
we're seeing.

4. Irc: While my computer seems to be having 
trouble with irc clients for the moment, I do 
fondly hold those days where I would visit the 
chat rooms and see people. Xane: I AM NOW 
ADDICTED TO HANA-CHAN! I bought a 
towel...a Hana-chan TOWEL! Ugh! What have 
you done?!

5. Cels.org - for obvious reasons.
