Hi! Thanks for visiting my userpage!
Here on Commons, I mostly patrol RecentChanges to catch copyvios and vandalism, as well as categorize new files that have not been uploaded with categories. I also do small things like correcting typos and so forth, and occasionally I will tag an image for deletion after deleting a corresponding page on en.wiki. I participate in deletion discussions here sometimes, but not very much.
If you are interested, my userpage on the English Wikipedia has more information about me. I am generally more active over on enwiki, so if you need a quick response to a query, you will be more likely to get it there than here.
