I know that the U3 platform is no longer officially supported by portableapps.com, but do you still accept user-submitted apps? I have Pidgin U3 in good working order I'd be glad to upload.

Like many devs, we no longer support the U3 platform at all.
Sometimes, the impossible can become possible, if you're awesome!
