I wanted to start a social bookmarking site and found about 5 scripts that had the potential to be built upon. Not only was this one the most affordable, but the pre-sales support was the most willing to answer a host of questions I had. While there are some features I'd love to see added, I was more than happy to build them myself once this script was installed. The script creator has been EXCELLENT with responses to technical questions. I would highly recommend using any of their scripts simply for this outstanding support.
