Alternative ChatRev clients
This link leads to marks client. It is not as simple as mine, but he has added some nifty features. Also check out the Protocol definition that he has hidden in the readme pdf.
The Scripter's Scrapbook, or ssBk is a commercial application, which uses the ChatRev server as chat facility.
Mail me if you want to make your own client. In that case you also might want to read this text.
