COPA Online was an instant messenger made in Game Maker. It had it's own domain name, copaonline.com, but that domain is now expired and owned by domain squatters. I promised to release the source GMDs as GPL a long time ago, and now I have finally got around to finding the source GMDs and other associated files, packing them into a zip file, and putting them online.

So this means that COPA Online is now open source, under the GNU GPL license (see readme.txt). Be warned, however, that there is no warranty, running the provided code is at your own risk. Nor is this code supported or actively developed.

Update 03/23/2007: COPA Online source package updated with GSGME.dll and settings.txt. I still haven't found the source to copaonline2.dll.
