I bought the open source version of PG Dating software all the way back in April because I wanted to customize it. I have spent 8 months now dealing with their horrible and inadequate programming. They say you can use PayPal but I had to pay my own programmer to 1) get PayPal to set up the monthly recurring charges, and 2) to communicate BACK to my site that they had paid! It was a NIGHTMARE. And now, after 8 months of this, I find out the programming is NOT compatible with Authorize.net like they claim, and that it will take another few weeks and $1000+ to TRY to make it work - and even then I'd have to host those payments on my site (which is a security risk and a huge pain). I'm so upset - if I'd known back in April what I know now, I would have spent the same amount of time and money building my own site from scratch. I beg you, don't take the chance - the programming is horrible. OH - and the version I bought didn't support their private phone calls for my users either, as they claimed they do - and they weren't willing to fix it. Nightmare after nightmare... and their hosting is so overloaded that my site moved at a snail's pace until I got my own server.
