Where would I post a question related to how to make a dynamic signature. It involves, web applications, coding, graphics.
I posted in web applications, and the question was closed. Where should I post it?
It isn't clear which forum you are using (I don't know whether each forum uses the same format).
Also the signature comes down to some sort of html and embed problem.
See these questions tagged signature to see an example of what can kind of [signature] questions Web Applications accept.
As long as your question is about how to use a feature of an application, it should be on-topic. Forums are more in the gray area. I have opened a meta topic on Web Applications to ask others,
Next time you should also post in the site meta, so that the mods of that site can track your problem. meta.stackoverflow does not cover all SE network site topic activities

You need to narrow down your question. Work at your problem until you have one specific problem. Then it should be easy to determine where it goes.
Also, you need more details. We can help you much better if we know what you're doing.
