I posted this question Which classic ruleset monster description might give information to use for complete home-brew game rules? for which I got a very good answer for which I'm happy I asked this question here. Now my question has been closed. I don't know how important that is I just wonder where I did wrong so I don't repeat the same error.
Since my question got closed I tryied to figure out what I could have done wrong, I figured that my tag homebrew was wrong since it is only meant for adaptation of existing systems and I changed it to game-design, since my question was about my own rules. However the question was not closed as off topic but as unclear. I got a perfect answer from SevenSidedDie, which couldnt be more on the point, so how can my question be so unclear to be closed.
One idea would be that people don't want specific questions about homebrew systems, but then why have tags related to this?
Ps: do I need to save a copy of the answer since the whole question might be errased?
