Multiple campaigns

[arnoldino]

Hello,

I'm new on this site, and I would like to ask for some informations
about the abilities of the OpenProximity interface.

First of all, I would like to ask, how multi-campaigns work?

The server sends a specific document to the user, and if the user
returns another time it sends another document?

I would like to offer some kind of category browsing to the user, to
decide which document wants he or she to download.

Is this possible with OpenProximity?

If yes, then another questions will follow, but first I'm interested
to know the answer for this one.

Thank you in advance.
Regards,
Arnold
