Is it possible to limit a person's posting?

have one person in our class that is posting constantly and other classmates are getting irritated with it

Under Admin Functins/Preferences/Profile Preferences, it appears to be all classmates can post messages or make comments or none can. I think feedback in terms of a warning to this classmate, who may not be aware he/she is offending other classmates, may be the best first step. If that doesn't work, then, in the interest of site unity, you may have to delete the offending classmate's profile.

I would hate to limit him. He probably is socially unaware. Others don't have to read his postings.

"He probably is socially unaware."

Curious 1): Is this a developed distinction or did this individual exhibit the distinction in e.g., high school? Curious 2): Are the posts over the line and considered as offensive (and why); or are they simply too voluminous?
I agree with Scott. First: a gentle but direct approach, and a mild admonishment may well be preferable. If that does not work then restriction should be exercised. Otherwise the offending behavior is condoned. What is the value in asking other classmates to just "not read" the posts if the administrator takes steps to ameliorate the offensive behavior? Am I missing something here?

Just to add: We have this simple and clear message (see below) on our Message Forum at the top - works well for us.

"The message forum is an ongoing dialogue between classmates. There are no items, topics, subtopics, etc. Forums work when people participate - so don't be bashful! Click the "Post Response" button to add your entry to the forum. Nothing should be posted that is: inappropriate; not germane to our Classmates interests; rumors / myths (from e-mails, the internet or any other source); vulgar or unacceptable language; etc. Thank You."

Yes, are they bothersome simply because they are so many postings, or are the offensive?

We have a 'Purpose Statement' on the Home Page for the web site that has stopped all issues of this nature.
