What About "System Security"?
First, we manage the bulk of System Security for you.
We have set you up with your own private secure database, and placed that behind an encrypted SSL or https system. We use "one way" encryption for all passwords and communications, and have a bunch of layers of security against hackers and mischief makers already built in.
This is not to say "there will NEVER be a problem" at one of our Member sites, but if you do your part and use strong passwords and such as a user, the chances are small.
