Some other software solutions out there may run ok with less than 100 members / subscribers might be totally unreliable and unmanageable with more than a few hundred subscribers.
If you expect to have more than 100 paying subscribers, make sure the software you are considering is being successfully used at sites with tens (or hundreds) of thousands of paying subscribers.
Otherwise you may discover the software leaves you stranded just as your site becomes successful.
Some of our sites have over 100,000 members while MemberGate continues to provide a reliable and stable platform for a business.
