Sure, but there should be a boilerplate at least:
"By clicking 'submit' you are contractually stating that the material you submit is henceforth released under GNU FDL. Though this site is "anonymous", we will log your ip addresses as a means to identify you, and though we will not provide you ssl encryption to protect your account and identity, you must know that any edits made under your username are your responsibilty, as provided under US law."
We might even mention the PATRIOT Act, as a way the US might enforce such law. ~S~
What's wrong with the current text. The only difference between that and the current text is that the current text sounds less like legalese and sounds less threatening. The current text is posted below:
