Greetings all round

As a new boy in town, I'd like to know whether this site facilitates brief written score quotations (in, say, MusScore or Sibelius), when, for example, I want to ask a question about a chord-progression or relative tonalities. Can I put these in as foot-noted (or end-noted) attachments or links?

This is chiefly with reference to classical or "Easy Listening" stuff, but it could be relevant to Jazz and R&B too.

Any thoughts or information, anyone, please?
