Not so much fun to have a forum without members.
And as Ron said, a moderator is needed to delete spammers
as soon as they post - not an easy task.
The spammers will register as users and then begin spamming.
There are actually people hired to do just that.
If you have some special information for teachers that is not
available anywhere else, you should do a website about that,
and ditch the forum ... just my opinion. I only mentiont this
because you seem to have a lot of technical aptitude not common
among most teachers I knoew.
