As far as I know it does not.

Max,

I don't want to think I am being rude. But the best advice I can give you is contact them. Tell them what you want to do, see if it does it. My experience with that system is minimal. I have helped two webmasters set it up. One was an earlier version.

The feature that I like mose about it is it allows you to offer trial memberships, but only give say the first two clips in a series or the first 20 pics. they have to upgrade to get the rest. I dont think site depth allows this but i may be wrong. BUT, I heard the new NATS version is going to rock. But, very expensive as well.

Please contact them and ask them your questions. Then post the results on teh board. I will respect you if you can actually answer that question.

They are the best at knowing what their system does and may even be able to tell you what the next version will do.
