Sass has a thriving community that’s eager to help out. There are several places where you can go to ask questions or help you debug problems. Before you do, though, make sure to check the FAQ.
The Haml/Sass IRC channel, #haml on irc.freenode.net, is a great place to ask short questions that you want answered quickly. Feel free to ping nex3 if he’s there to get his attention quickly.
If you have a longer question (or no one’s around on IRC at the moment), the Haml/Sass Google group is a great place to go. You’ll usually get a response within a day or so; sooner, if the developers are paying attention when you send it.
