I've been a member of ravelry.com for knitters for quite a while and love the clean look and simple interface of the site and wondered why there was nothing of that quality for sewists. It looks like there is: mysewingcircle.com
Right now it is in the baby stages, but so far there are over 800 members. The owners are really paying attention to the members and implementing their suggestions. This may be the site I've been dreaming of.
Go take a look: mysewingcircle.com
