I have a question about wiring up an ethernet face plate and I'm unsure whether I should ask here, StackOverflow or Home Improvement.
Should I ask on multiple sites or just the one specfic site?
I think both here or Home Improvement would be fine.
Whatever you do, don't cross post please — just ask your question on one site.
It would be acceptable here, but you'd likely get a better response at SuperUser
While I'm not sure we have that many questions on this topic, feel free to ask it here, and if you don't get a response, we'll migrate it for you.
If you are looking to just wire up the face plate, then superuser would probably be best. If you have questions about how to run the wire, that's more of a DIY thing.
