I am considering amember pro. The only question that I have is: What special requirment will I need for my web host provider. (For instance, I know that my web host does not support IonCube Loaders. What specialties do you require, so that I can ask my web host provider if your script can be installed and work properly. Thanks for any ideas. P.S. I am writing, if I need to backspace, your letters begin to cancel eachother out on this forum.
I use Godaddy as hosting company and just discovered that they do have Zend Optimizer on their servers as I had the same problem that you are talking about. Loading the trial version with Zend worked after we had to change the data base version to 4.0 instead of 5.0. Your web host may work that way too.
No it'll run on Windoze provided the implementation meets certain requirements. Download the test file at http://www.amember.com/downloads/tester.zip ,upload and run it to check.
