How can I check a question's correct place, acceptability and plausibility before posting it on Super User?

Is it possible to check the correctness of a question in advance here on Meta Super User? Or I send my question to some admin and the admin will indicate to me where is the right forum/place to put the question and how it should be edited and tagged so not to be blocked or closed?

So the question that I actually want to ask on Super User is:

When I use Firefox I regularly clear up the Firefox's cache by:

Menu -> Settings -> Privacy & Security -> Cookies and Site Data -> Clear Data -> Cookies and Site Data/Cached Web Content -> Clear

I was wondering is it possible to write a Bash script that would do this automatically every 2 minutes? Or is there any other way to bring Firefox to clear it's own Cache automatically?

I was thinking to give the next title to the question:

'Bash script for automatically clear Firefox's cache'.

And to tag the post with 'bash' tag.

Would such a question be allowed to be phrased in this way?
