Hi,I'm fairly new but I can try to answer a couple of your questions.
The slow response with IE, I'm not a fan of IE cause I"ve just encountered too manyproblems with it. You might want to use a different browser, like mozilla firefox,or Opera. I use both and highly recommend either. Firefox is probably the easiest to learn.
next, revising. I came here from a paying site where we still had to revise thru ebay. someone will correct me if i'm wrong, but I think that is standard with listing services.
I don't use auctiva's insurance or checkout so I can't help you there,sorry.
