Has anyone been sued and lost the case for code posting to Perlmonks? Or for code posted to Usenet, which has existed for much longer, and covers many more languages than Perlmonks does? As long as Matt Wright walks around a free man, I really don't think this is an issue. Besides, if you now put a disclaimer here, it kind of suggests you are accepting liability for code posted here in the past.

But if PM were to put a disclaimer here to avoid posters from being sued, I suggest they would hire a lawyer to write the legalize - it would be bad to pick a wording that isn't going to hold up in court.

Alternatively, post all your code as AM. ;-)
