+darum ging den Auftritt von oddmuse.org aufzuhübschen. Also du/ihr

+
+Welche Lizenz das ab besten leisten, da hab ich keinen Schimmer.
+
+Schön wäre, wenn irgendwo ein verweis auf "Falky [falky.de]"
+auftaucht, der soll aber nicht bei jeder Verwendung auftauchen,
+sondern irgendwo 'auffindbar' an 'zentraler' Stelle - halt irgendwo
+auf der Homepage, dass ich darauf verweisen kann und dass niemand was

+logo für ein anderes Projekt verwenden möchte, kann man ja höflich
