TinyMCE CF GZip has moved from github to sourceforge
February 27th, 2009
With the CF gzip compressor now part of the TinyMCE, further development will commence at SourceForge. Right now (and just for link’s sake) it is at github.
Old: http://github.com/WebVeteran/tinymce-cf-gzip/
New: https://sourceforge.net/projects/tinymce

Getting a javascript error when I try to use this…
Can you be more specific?
