(Also if this is really how you wanna do this, we'll need a short nickname for you, Anonymous Helpful Person.)

The nickname convention at enwiki is the first pair of IP numbers. So this is the anonymous helpful person 197.218, and there's another widely respected anonymous helpful person at 64.40, etc. ;-)
