Unity chat limits / removals.

[Dzspdref]

Can we possibly get limitations for Unity chat members:
Possible options:
1] Character does not change zones for 30 minutes (idle/afk, bazaar, farming, in party, etc...) so Unity chat for advice/help is not needed, so remove them.
2] Character does not post a chat in /unity for 30 minutes, so remove them.

#2 can and will be easily circumvented by someone coming up with a script to have it automatically do something within that time if afk, etc... so option 1 seems best in my opinion.

If/when they re-zone to another area, they get the "chance" to get back in to their Unity just like everyone else, as long as there is an open slot for them.

We have multiple other timers for items we use that have timers on them, so can this also be implemented?
