Hello, I am from Germany, a country in the middle of Europe.
My interests are mainly geography and landscape/nature topics, especially protected areas.
On Commons I often sort photos and try to create a better streamlined category system for protected areas, aerial photographs etc, including multilingual descriptions.
On Wikidata (and by related edits on various projects) I help with interwiki link corrections, and try to improve structured data items in various ways.
On Wikipedia i edit mainly local/regional articles, protected area lists etc.
A really great project is Wiki Loves Earth, an international photographic competition with the subject natural heritage (protected areas). To discover its potentials you can have a look e.g. at my little collections for the German subset of WLE: 2014, 2015 and 2016 (all photos made by other users).
Do you like puzzles or tricky riddles? – On Commons we have thousands of good images lacking useful descriptions and categories. Many of them can be found in the various subcategories of unidentified subjects. Here are three examples: maybe you can help with identification?
