Ok, so in the source files I would replace ```Copyright 2005-2012 Enrico Tröger <enrico(dot)troeger(at)uvena(dot)de>``` by ```Copyright 2005-present Geany developers and contributors``` and similar in the About dialog? Or any better suggestions?
While at it, I would also remove the "All rights reserved" notice as it seems not necessary at all nowaydays (according to Wikipedia).
