Email, please confirm receipt
And deny you the fun of working it out for yourself? So much for Sherlock...
Forget it, I'll just forward her the email I sent you. Maybe she'll take me up on the offer, lol
Given that you have linked to the list of "Ninjas," I am going to speculate that Brxbrx wants some edits made in bot mode so that they are invisible on Recent Changes.
You can show bot edits in RC anyway. Anyone who feels responsible for "patrolling" (for lack of a better word) RC should have that filter off by default, and only switch it on briefly as a filter should there be any extensive bot work going on at the time. And unless you plan on doing genuine extensive bot work - the list of people who do that is about 3 names long - then there's no need for ninja rights to be granted.
