I've seen the tag Corporate-Finance being used, but I've also seen a question closed...
I would like to post a question on the basic principle of Assets=Liabilities + Equity, and how to finance sales growth. Is this ok on this forum?
My standard advice in this situation is that you should post your question and see what happens. Especially during the beta, it is useful to see how a broad range of question types go down and nobody will be annoyed if it turns out your question isn't a great fit.
