I've used videos and articles from this site for all kinds of things on my membership site. I've also enlisted David for wordpress/amember integration and some other tricky issues that I either messed up and he fixed, or a knew were over my head to begin with. David's responsiveness is amazing. After trying to handle an upgrade myself, and getting the white screen of death on a busy site, David identified the problem and fixed it in minutes. I've found membership here essential to being able to run my site. Thank you David for the knowledge and the service.
