RE question

[Ken Loomis]

~sdpm~
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.

thanks,
Ken Loomis
