I've been editing on Wikipedia English since September of '05, though I'm not a particularly active editor. Usually just a few grammar updates here and there. Particular subject matter interests are:
- Private spaceflight
- List of Oldest Living People
- Lines of succession (monarchies, religious leaders, etc)
- Country histories
- Meta-wiki list of Wikipedias
I do some light editing on other language Wikipedias occasionally. Specifically Esperanto, Portuguese, and Spanish. I'm not fluent in any of those languages, but effective enough to recognize occasional typos and phrasing problems or add small additional notes. Esperanto is probably the one I'm most capable in. I also can comprehend some Japanese and Swahili, though my understanding is quite rudimentary in both.
