I just tested
Nova Submitter yesterday and am REALLY impressed. It's not quite as easy to use as Chameleon and it doesn't submit to quite as many sites, but my test galleries have gotten 50% more traffic to them in 24 hours than my Chameleon submits usually do.
I'm still hooked on Chameleon, but this Nova Submitter is my new #2.
