Hi all

I need a functionality on openser.
The functionality would allow users to save on the server
- a message,
- a time and date
- and a group of uris,
and at the given time, the server would send the message to each one of the group of uris.
This functionality would be useful for users to send reminders of events to a list of uris.
Are there any modules on openser that do something like that?
If not, how could I implement it?

Thanks
