Forum Maximum Chars Allowed in Moderator Notification in Forum Manager?

[محروم.كوم]

Under the "Forum Manager" ... if I select a Forum to edit ... there is an option to notify specific e-mail addresses of new posts. It seems to work fine if I put in one or two e-mail addresses ... however, if I put in, say 20 addresses, nothing happens.

So, a few questions:
(1) What's the maximum character length allowed in this field?

(2) Can it be modified? If so,
(3) Where would I do that?

This might solve some of my current issues.

Thanks All!!! __DEFINE_LIKE_SHARE__
