It's only a matter of time before e-mail harvesters fix their code to 
accommodate &40; etc. It seems like a simple thing to change in a perl 
script (assuming that's what they're using). Perhaps the Forrest's 
obfuscation system might someday give the opportunity to customize it 
(from skinconf.xml):


That way, people could add their own (if they so choose):

Of course it would always default to the best thing we can come up 
with, provided <obfuscate-mail-links-char> (or whatever it's called) is 
not set...
