In the beginning, there were Skype forums, where developers could get support from each other, and occasionally, Skype staff. Then, Jira came and it became possible to track each individual issue separately. Free of charge, to the benefit of the entire developer community, "as is" and on basis of best effort.

But "best effort" and public communication wasn't enough -- for some developers, at least. You've asked for specific response (and resolution) time targets. You've wanted to keep your questions and our answers private -- at least until you get your product onto the market.

Your wish is granted. For a small fee, we will now give your support requests privacy and priority. We call it professional support -- because it sounds better than "support for professional developers"
