There used to be Trac instances here that I used for bug tracking, but these have fallen into disrepair, are no longer available at this time, and will probably just be decommissioned outright. (I was the only one who ever used them, anyway.)
The corresponding git repositories are still viewable on the stump.io gitweb, with working clone URLs available there too. I also have some other projects on my GitHub account, including mirrors of some of the ones here.
Releases are on ftp.stump.io (available via HTTP at http://ftp.stump.io/software/, anonymous FTP at ftp://ftp.stump.io/software/, and rsync at ftp.stump.io::software
).
There is also a Mailman instance here with mailing lists pertaining to some of my projects. View the list of mailing lists here.
