There are plenty of places around where you can get your Inkscape questions answered, including the inkscape forum, inkscape answers on launchpad, and the inkscape section on the graphic design stackexchange.

But if you need an answer to a question in real time, the official #inkscape user channel on is the best place to go.

Never used IRC before? All Good, as the new inkscape website now has a web app that lets you connect directly through your webbrowser to all the knowledgeable folks in the #inkscape chat!
