I asked a question (to be specific, this one) about four months ago and got a completely satisfying answer.
In the meantime I continued my project and built my own solution for the problem by slightly modifying the answer I have gotten, and new questions concerning the same project turned up. They're quite specific and can't be asked in a meaningful way without referring to the project itself.
How should I ask them? Should I ask them as comments in the old question? Should I open new questions? Or should I do something different?
