I've tried many other user management systems, but every one has been somewhat buggy. I had to disable various functions because they just did not work properly. Until now! I've installed aMember on two sites and EVERY aspect of this system has worked flawlessly I even had a plugin made that automatically adds new users to a forum on my site. A great feature! If interested, you can see how it works on my sites: http://www.itcert2go.com http://www.network-certification-training.com
