Yes I am. I am currently up about 300 uniques a day with only 15 or so DWPG sites up. The DWPG and ProSubmitter have paid for itself in about weeks time. This is from directing traffic at a measly $1.30 payout offer (but it converts very well).

I have been going the free host route. Most of my DWPG sites are indexed 100-200 pages deep within 16 hours and some of those are indexed even without using pro-submitter on them.

As with any software these two apps take trial and error before you see big bucks. I am confident, once I find the right match in keyword density, keyword list etc. I will bank hard.
