HI,

Dave't answers below are right on target.

One other consideration is the interoperability with managers.
Some poorly designed managers make assumptions about
community string values, such as ONLY ASCII letters and digits
(no spaces or punctuation characters). Also, some agents
also have the same restrictions because they save their
configuration in ASCII text files and the parsers for
the files cannot cope with community string values
that are not just ASCII letters and digits. 
So, testing on one system (manager or agent) is not
applicable to all.

Sad situation.

And remember, a community string value is NOT a password.
