Actually, Yahoo strips out a LOT of html and all Java script. I finally got an auction to list properly with AW2K.
I use several tables within the main bordered table - and Yahoo just made a mess of the whole thing. I finally just made a stripped down template without any tables, and the most basic of html commands (simple things like <center> instead of <p align=center> made a difference).
Can't really blame AW2K for this one....Yahoo made just as much a mess of my cut/paste html auctions.
I just started my first Yahoo auctions this morning. It's cheap...but I got a feeling all the trouble won't be worth it. Ebay rulz...
