Your question is slightly different that Brian's. Here is a copy paste from what I replied to Brian:

------------------
A long lived conference is one that runs for months (chat sessions on the internet seem to run for that long). They are not repeated, but instead are constantly running.

An administrator, for maintenance reasons, might want to de-activate a conference for a short period of time.
------------------------------

In this case, there is no difference in meaning when you say "stopping" or "deactivating" the conference. But since you are stopping the conference for a short period of time then restarting it again, and you do not want to affect the overall start and stop time of the conference, then you are really just making the conference inactive. Maybe inactive in the wrong word here. Maybe suspend is a better word. You are suspending the conference.

The other scenario is that the conference does not have to be running yet. Someone might schedule a conference starting Monday next week and stop 3 months from Monday. Moments later, the administrator decides that in 2 weekends time, he will suspend all running conferences. The administrator can immediately schedule such event before the meeting starts on Monday.

Brian was asking what the difference is between de-activating a conference and conference repeats. I guess you can think of as such, but it is not the same thing. Certainly the solution can incorporate both, but the 2 need to be recognised a separate requirements.

I hope what I state above answers his question (and your for that matter :)

Hisham
