My page at Wikipedia is here. My first commons username (which links to here) was User:PDTillman. Since that's the name on my TUSC account, and where I keep a record of my Commons uploads, that's the one I'll mostly keep using, except for the unified login bit.

My recent contributions to Commons are at Category:Files uploaded by PDTillman. Over 4,350 images uploaded and over 33,000 Commons edits, as of 9/3/2024.
