Based on this question I have an unclear understanding of when and how to use the Houserule and Homebrew tags.
Homebrew tag has some clearer guidance:
For questions about homebrewing new rules content for an existing system
That seems to be imply the tag is for when you are creating, or homebrewing, new content and asking about it's balance, etc. If that is incorrect, we should probably change that language.
Houserules tag states:
House rules are small fan created additions and replacements to core rules in a rules set. In most cases, they are not officially sanctioned by the designer, in contrast to optional rules.
Unlike Homebrew, this tag does not talk specifically about "homebrewing new rules", but instead seems to be more general.
If we return to the question cited above, it is unclear to me as to whether or not the House-rules tag should be included.
The question is asking how a house-rule item, the Electrum Shortsword, and how it interacts with the existing rules regarding Lycanthropes.
My concern is that because the item is a non-standard item and was house-ruled in creation, we can try to answer based on the existing rules but that any true answer needs to understand the specifics of the house-ruled item and the house ruled tag should be included.
All in all, when a houseruled/homebrewed item is being discussed and a question revolves around it's interaction with existing rules should the house-rules tag be included as an identifier for the querent and answerers?
