MBS is now a sponsor and if you are not going to Salzburg or San Diego anyway, you could still join this conference in Berlin. Especially if you are from Europe and like to talk about our plugins with us.
We'll be there and make two presentations. First one about the MBS Filemaker plugin and a second one is about Mac goodies like Syntax Coloring, smaller Runtimes and Gatekeeper.
If you prefer a German conference, maybe you better go to the Filemaker Konferenz in Salzburg in October from 17th to 19th. Or come to San Diego from August 12th to 15th for the Filemaker DevCon 2013.
