If you need help with any of the projects I contribute to or have contributed to, please let me know!
I'm most active on the English Wikipedia (admin) and Commons (former admin), though I do visit the Simple English Wikipedia (former admin) and Meta from time to time. I used to be part of the OTRS team and expect to rejoin them in the future.
While I am not at all active at the Explain XKCD (non-Wikimedia) wiki, I did some set-up work there a few years back, when it changed from a blog to a wiki. For some reason, I remain an administrator there.
