Submitting a support request is the most direct way to contact us here in support.  Another great way to get support is to visit the SL Partner and Customer Forums:

Partner:

Customer:

 https://community.dynamics.com/product/sl/f/35.aspx

The advantage of posing a question at one of the above links is that it will open your question up -- not only to us here on the Microsoft Dynamics SL support team, but also to other Partners or Customers who may very well have seen the same issue or know the answer to your question!  Stop by and ask a question or click a few threads and see if you can help out another Partner or Customer.
