I have received some things I don't need, and I have lost some things due to some wormy thing in my starting soil. I have updated my list to reflect this. There are flowers, herbs and veggies on both my wants and haves.
I just updated my seed exchange list as well. I noticed you said something about carrots on your "want" and I have a full packet. The "common plant" sounds interesting! Take a look at my list and see if there is anything you may be interested in if you want :)
