Since you asked, well, OK, none of you asked, but I've done it anyway. I've setup a merch store where you can get T-Shirts and various other things, mugs, clocks, etc.
buy something now.
If you spot anything wrong, or have any requests or suggestions, let me know.
2022 Update: The Merch store is actually still open, although I don't think anyone has bought anything in ages.
