I don't; I prefer questions (and more importantly, answers) being somewhere they're publicly accessible, so they can help more than one person.
I'm not sure if I can wholeheartedly recommend this engine for new projects anymore since it just barely survived the GMS1-->GMS2 transition (it's originally made in GM6, so this is the third layer of compatibility functions...) and Yoyo have hinted at new 3D tech being on the roadmap, it might be completely obsolete in the near future. Depends a bit on project scope, of course.
