Thank you for your open-source contribution!

Under funding from the NLM, we are developing a website where you'll be 
able to list your software, find other people's software, have forum 
discussions, etc. regarding open-source medical image analysis software.

The site (you'll want to use a bookmark for this!) is

The site is NOT ready yet...but let us (jjomier at cs.unc.edu and 
aylward at unc.edu) know if you have suggestions.   I'll also add your 
software to the lists that we are compiling!
