I have contributed small bits to many pages, correcting typos, obvious errors, mistakes from my areas of expertise and have written longer pieces of some chess composition pages. In 2005 I have participated in two projects Wiki Syntax and Disambiguation pages with links. In 2008 I was involved in the resolution of Hungarian-Slovakian dispute. Currently I again disambiguate time to time.
As reader
As the former trivia site questions editor I have been using Wikipedia heavily as mostly independent source of information for checking all contributions. Also, I still like to browse through Wikipedia almost randomly and suck into my brain the facts uncovered on the way.
