One thing that put me off directory submitter was the default search engines. Basically, I tried exporting my lists - replacing the original directory list with my own custom one - However it either saved the original list and the custom list, or none at all
This was the trial version, but it put me off buying the new one. That and you couldn't specify niches.
If they've fixed that (have they?), and if the fact you couldn't specify niches was a trial limitation, then I'll be more happy to purchase.
