Are you asking what the subforums are for?
Meta is to talk about the forum, this is where this thread would belong. Mining support is support for mining Bitcoin, not to be used in case of any Altcoins. Technical Support is for more technical/advanced topics, like backend stuff the typical user has no hand in.
Actually tech support is meant for bitcoin core related issues. What you describe also stays, unless it would better fit in "project development" (e.g. Im developing Y and need help with X); beginners and help (basic questions); development & tech discussion (protocol specific questions); service discussion (e.g. I send TX from bc.i and I get error Z) or one of the other wallet specific boards.
