For all those websites and programs that allows you to post links, but are broken enough not to allow you to post anything other than http links I have created the AptUrl proxy:
Test it out: Install Inkscape
Simply put the link http://doctormo.org/install.pl?package_name and your viewers will be referred to the correct apt uri. I’ve made this in response to the bad support for links in deviantArt, seriously who would detect the use of http alone as being a link to http://, the mind boggles at what kind of code they have for link detection.
Anyway this gets around that little problem and you might also find it useful for your communities.
