Any other information: I have intentions to work on the wiki, but the administrator seems to have closed his account (his info was "AKA account disabled"), and therefore he doesn't seem to respond anymore. In the meantime I will try to contact him. There are no other active editors outside of User:AbercrombieFizzwidget, who last logged in on 17:44, July 31, 2015, but last edited on 19:42, June 22, 2014.
There are some administrative features I want to access, such as the CSS, in order to stylize the themes of the wiki.
Since the game content of Piano Tiles and Piano Tiles 2 are small, there doesn't seem to be a necessity to create another wiki like "Piano Tiles 2 Wiki" exclusively for Piano Tiles 2.
