I'm happy to report several successful mixes using this service. I do have a couple of questions though.

I am in a mix right now that limited me to .2 BTC and I think I know why, but the WARNING! message that pops up is unhelpful in explaining why and is a bit disconcerting.

Also the first few mixes I did were done very quickly but then it seems like they got progressively slower until the present mix I am in has been over 12 hours.

Nice service... just wondering...
