Not to speak for Alex, or the aMember team, but the answer is yes. aMem can protect certain pages or areas and grant access only to your active members/subscribers. aMem works with typical html based sites, integrates with most CMSs (Joomla, Mambo, etc.), integrates with popular Forums, and has payment plugins for most payment systems. Browse through the Forum and you'll see that there are plenty of users who think very highly of both aMember and the Customer Service. Provide a bit of info about how you plan on using aMember and maybe someone will provide some advice.
