My edits are various, and intermittent, and, well, wandering.
I mostly contribute in areas where I believe I have some expert knowledge, some large, some small, some just noticed in passing. The "technical Wikipedian" editing I leave to the experts, who have my admiration and gratitude! Occasionally I try to sort out some grammar or spelling. I delight in joining the rush to smash up vandalism.
I'm not a linguist, but I have a workable relationship with just about any Romance language (including elementary Latin) and similarly with the Germanic languages. I can decipher Cyrillic. Sometimes I edit Wikipedia pages in languages other than English.
I have created only one whole individual page. You may be able to find it.
Wikipedia has proved itself very valuable to me. I like to help to improve it.
