I will now be resigning as OTRS admin and relinquishing oversight. That's mostly symbolic as I've not been active for some time, and several people (including Kat) know my full details anyway. My first and middle names (Lisa Carter) are fully public as part of my work at Wikia, but I choose to keep my last name private. I believe everyone in these positions should have that option.
You would only be giving the information to the foundation - I don't think they'll give it to anyone else (short of a subpoena, I guess). What benign reasons can you really have for not wanting the WMF to know who you are? Seems like slightly excessive paranoia, to me.
