The vast majority of the homebrew questions we get are asking us to review their homebrew, either directly ("Is this balanced?") or indirectly ("What LA should this race have?" or "How much should this magic item cost?").
However, we also get a nontrivial number of questions about homebrew that are not asking us to review it. Here are some examples from the past 3 months:
- How can I add an alternate racial trait to a race in PCGen?
- What are the mechanical balance issues with a playable race with more than two hands?
- What variables do I have to take into consideration when I homebrew armour?
- What benefit would races with extra hands have?
- How are spells made permanent in 5e?
- Does a Snake Sword user get an AoO for an opponent moving from one threatened square to another within range?
- How would I state a creature to be immune to everything but the Magic Missile spell? (just for fun)
- Is it still a binomial distribution when rolling dice with different probabilities that must be met to count as a success?
- What are the ramifications of creating a homebrew world without an Astral Plane?
- Modifying Gumshoe One-2-One difficulties for non-horror campaigns
- How do I prevent a homebrew Grappling Hook feature from trivializing Tomb of Annihilation?
Note that a lot of these seem to fall into two categories: "What are the things I should know about X before I think about messing with it via homebrew?" or "We're using homebrew Y, how can/should we handle situation Z involving it?"
Should we split/rename the homebrew tag into some larger number of tags?
