Rumour has it that people used the GothdeCoder 3.x often. GothCode versions 1 through 4 inclusive are copyrighted by Peter Caffin. Try my goth encoder CGI script yourself. Peter's written some wacky HTML for all your Gothcode support needs. That's just, since he's the developer for it.
Some samples are below.
Just like GothdeCoder 3.x, you too can have a button on your homepage that does translations. Just read the HTML source for this document. You won't have the cute button, either. Now go visit my Convergence III gallery and pages. Tingoth will serve GC'98 translations.
