A member of one of the sites I participate in is experiencing a bug exclusively on that site. Since being concrete is generally helpful, this is the bug.
There is some concern over whether bugs get noticed on per-site metas, so I figured I'd ask to clarify: if we post a bug or a feature request on a per-site meta, do the Stack Exchange devs notice it, just like if it were posted on Meta Stack Exchange? Or do bugs and feature requests requiring their attention exclusively need to go here?
Really this is a duplicate, although old posts might be somewhat confusing to new users because of the switch from meta.stackoverflow.com to meta.stackexchange.com so I think this is worth answering again.
For bugs that affect only a particular site (for example, a CSS bug in one of the themed sites, or a bug that is data-dependent), please ask on the meta for that site. So: a bug that only affects bicycles.stackexchange.com should be posted on bicycles.meta.stackexchange.com.
There are also many bugs that affect all sites. Those bugs should be reported on meta.stackexchange.com.
However, the above is just our guidance on the right audience to report to; we have ways to search across the entire network, so bugs posted on any meta will be noticed.
I'd expect the default forum would be a question on the site's own meta
That's correct. First, bring it up on the site specific meta - the community (and moderators) should all be involved in deciding whether a feature should or should not be enabled (and possibly what form it should have).
but I don't know if the moderators there would necessarily have the power to effect a requested change if they wanted to
Some things moderators can do, others they can't, but can escalate to Stack Exchange employees - the community managers.
Additionally, the community managers do monitor feature requests on all meta sites, so they will see such requests and act on them (assuming the community comes to a consensus).
would such a request need to be raised on meta.SE to be seen by someone capable of considering and delivering that change?
As I outlined above, no - such a site specific request should be raised on the site specific meta.
There is (to my knowledge) no standard process, but from what I know, the correct place to ask about site-specific anything is the site meta.
Only feature-requests and bugs affecting the complete SE-Network should be are often better off on MSE, because of the larger audience, which is often very involved in already existing requests and reports.
To my knowledge employees regularly patrol site-specific metas looking for new bugs and feature-requests (which are probably added to the issue-tracker subsequently). Additionally every mod can contact the team directly. But there's a lot of open bugs and a lot of open feature-requests, so don't be discouraged when it takes some time ;)
