I just finshed my first submit, so I'll report back here...might be nice to see the opinion of someone not involved with the program and with more than 1 post.
All in all, the program is easy to use. Not quite as easy as Chameleon, probably on par with Advanced Submitter.
I was a bit disappointed when I was selecting niches for my gallery. By the time I was done, I had just over 300 sites to submit to. That might take some figuring out on my part. Because the database seems to be a decent size.
The thumber is great. The Chameleon program builds a TON of different sizes. Again, this would probably change with a database the size of theirs.
The Confirmer worked like a charm. I bought the Chameleon Confirmer, so I probably won't put this one to use...but you never know. It works properly, which is more than I can say for some of them.
Give it a shot and check out the two week free trial. I got hang of the program and blasted out my first submit in about an hour.
