There are several ravelry groups for avid sewers. This is one of the groups I joined when I first got started really sewing seriously. Lots of fun projects posted there. :-)
This site is meant to be sort of like ravelry but it is rather new and I can't say I have spent a lot of time looking at it. I was the same way with ravelry when I first joined too so I am sure I will eventually start using it more.
Enjoy your new machine. Lots of blogs out there with fun projects. My feed reader is full of project ideas every day.
