Baseline membership reflects that our do-it-yourself service is designed to be used without individual support. Consequently, support options are limited, but typically unnecessary.
Most of the information members need is maintained in a detailed technical FAQ (available here if you are not yet a member).
When members need a little more help, they generally turn to our community support options. We have a member forum populated by some very, very smart people (including our staff), and members can view and contribute to a wiki that provides a rich variety of perspectives on tips, tricks, and how to get various things to work.
We also offer a specialized type of support, called assistance requests, for specific predefined actions that you need us to perform on your behalf. These are very limited in scope, highly automated, and are often designed to smooth over features that don't have a UI in our control panel, because they are specialized or rarely used. Baseline members also have the ability to report perceived problems with the system, although that channel is one-way; it is not a way to obtain help or support.
These options are sufficient for almost all of our members. Those looking for more can evaluate whether the individual support option included with subscription membership meets their needs.
