I have been using DC++ since October of 2002, when 0.181 was current. My first contribution to DC++ came in the form of a one line patch to 0.231 that prevented the just-added “disconnect users who leave the hub” option from giving a free slot to people getting your file list or a small file. I’ve contributed a lot of small patches to DC++, though there are a fewer larger ones here and there (MAGNET-URI support, for instance). Nowadays, I run and maintain the DC++ website in addition to contributing code.
I go by GargoyleMT on the forum and many places, and I’m usually credited as “garg” in the changelog.
