I maintain a small number of official SlackBuilds. You can consult the list of SlackBuilds I maintain at the project’s website.
My SlackBuilds are also available at my gopher site.

Should you find any bug, want to send a patch, or otherwise discuss any issue regarding any of the SlackBuilds I maintain, you are encouraged to send an email to the SlackBuild-users mailing list.
