Pattern Review has a message board.

I second http://sewing.patternreview.com/ especially since you say you're interested in sewing clothing.

Along with a Message Board, there is a Pattern Gallery where members post photos of clothes they've made, what pattern they used, what they think of the pattern, and comments on the clothes by other members. The pattern reviews are also cross-referenced, so if you think you like a pattern, you can click on a link to see all the reviews of that pattern.
