Perfectly fine to ask about MicroMod Teensy here. It is officially a Teensy board and uses the Teensyduino software.
The main etiquette I would urge, not just about MicroMod but with everything, is to consider people who will later find the thread(s) you've started. Especially when more than 1 thread is started, please share any answer with links on all the others. Weeks, months, or even years later people may find those threads by searching. Few things are more depressing than finding your exact question was asked and nobody answered.
