When I went to download a ThunderbirdPortable today, SourceForge told me that I might like "PortableApps.com Extras". I checked it out, and the page is called "PortableApps.com Extras by sag47" and it contains some "portable" programs.
This sounds like infringement and something that SourceForge shouldn't permit.

I think that might have been kai's project for hosting apps he was working on for release here. It hasn't been touched since 2010.
Sometimes, the impossible can become possible, if you're awesome!
The site does look old (checking the dates) but the files can still be downloaded.
"PortableApps.com Extras" appears to infringe on the PortableApps.com brand. Since that brand is yours to protect, you can ignore it if you wish. I'm just doing my part.
