Hi, again Gleb.
I'm disappointed that you didn't respond to my second post. I did wind up getting your plugin to work on my client's site, but for $99, it should be in your best interest as a budding entrepreneur to help your paying customer base with their issues in a timely fashion.
Aside from my gripe about your non-response to my second post, I would like to say that your plugin does work like a charm. Payment is handled smoothly by PayPal via our Premiere Business Account with Web Payments Standard, and the automated member creation in WordPress is a real boon.
Consider this a testimonial to the relative ease of use and relative strength of the plugin you've developed. I would however, strongly urge you to put your customers' requests for help at the top of your priority list if you really want to hit a higher level of success.
