I bought the commercial version and have had great support from him ... :up:
Yes, I agree that at times the response has been a little slow, but essentially it's a one man company so I expect gaps depending on other priorities and real life things that happen. I also take into consideration that it's not a hugely expensive product that I would expect to have a 7x24 help desk available, but for me, it's more akin to shareware where support is proportionate to cost. Nobody's going to make a living selling mods to support vBulletin.
He's been really excellent in gradually working through our individual issues and solving them, some of which are due to our own site being highly customized with additional other mods. This latest release is a leap forward and is now operating really stable on our site. It's been an excellent addition to our site and our members love it.
Remember, over used it's like anything else taken to excess and can be annoying and cause problems. Used effectively for the right purposes, it can really add value and differentiate any site from regular vBulletin installations.
I'd recommend folks try the limited (number of links capped) free version here and then ask your pre-sales questions before you buy, to make sure it's going to do what you want it to do.

Doug
