Support team 
Hello, I notice you have been answering questions at the support desk, any interest in joining the support team? -PatPeter, MediaWiki Support Team 20:35, 3 January 2008 (UTC)
- Hmm, that does sound somewhat appealing. Why not? I'll add my signature to the list. I have been getting more active here lately, on account of my own wiki experimentation. :) Thanks for the welcome! — Tuvok[Talk/en.wp] 23:04, 3 January 2008 (UTC)
- Signature add-on for the support team is at Project:Support_desk/Support_team#Official_Sig. -PatPeter, MediaWiki Support Team 15:07, 10 January 2008 (UTC)
Hello Tuvok, you know how large of a contributor I am here at this wiki. I was in my opinion unjustly blocked from Wikipedia. If you could put a word in at wikipedia:User talk:PatPeter, I would be grateful. -PatPeter, MediaWiki Support Team 17:03, 24 February 2008 (UTC)
