This is an alternate user account created for privacy protection. It was created without any illicit intents for simple edits of non controversial topics (mostly regarding detailed geography of the Czech Republic). I use it only occasionally when working on articles somewhat related to game of geocaching. Using my regular Wikipedia account in these cases would compromise my real world identity.
And a note for geocachers trying to solve GCZPN3: There is nothing of interest on this user page, you can return to the suggested article. :-)
