How about the editors coming up with a single, recommended style for all posted code, and intergrating a pre-configured PerlTidy into the message board? If a monk enters Perl code within code tags, he could click a button and have it formatted with PerlTidy.
I've used PerlTidy only three times with intervals of several months, and I always forget that it doesn't have a .pl extenstion and I always try running it at the command prompt without prepending "perl," which doesn't work. I've had other problems, including not being able to use the standard installation procedure because I couldn't get nmake to work on Windows. The installation instructions aren't for beginners, and I figured some beginners might like a PerlTidy web application. Then I thought of the Perl Monks feature.
