Thanks for all the tips! I knew FTers would come through. And I will need to do some research, so while this is a good idea to get rid of good things that I'm not likely to use, won't be offering them for eBay or craigslist this weekend.
Also like the idea of trying some smaller items such as books & dvds to get my feet wet & build up a good reputation.
And yes a lot of the dresses/suits/evening gowns are size 6/8.
Cheers.
