RE question

As a web designer that enjoys programming, I joined this group a few 
years ago hoping to become proficient at PERL (or, is it Perl). I have 
learned a lot from looking at the exchanges here, but have to admit that 
RE's still baffle me.

I host a discussion board that is apparently being Spam'ed by hackers. 
The board is in Perl and I would like an RE that will strip everything 
except alphanumeric characters from the subject. For example, the 
subject line should only contain A-Z, a-z & 0-9.

The subject line is contained in $FORM('subject'), so I'd like an RE 
that will replace the contents of that variable with the stripped 
version. also, I may decide to allow periods ('.'), and would like to 
see how I'd have to modify that RE to allow that.

If anyone can help, I'd appreciate it.
