2. claim ownership of nodes initially generated by Anonymous Monk
Personally, I would be more interested in having an option to
claim/prove that I'm not some Anonymous Monk :)
More than once, when replying to anonymous nodes, I've found myself
in the situation that - due to the specific context - it somehow felt as if
I had created the node myself anonymously — such as you could in
theory do in an attempt to gain XP (by posing the questions
yourself for which you have good answers...), or to frontpage your own
topic (posted anonymously), etc.
Sometimes, I'v even just not responded to anonymous nodes for that
very reason.
