Multiple bad or dead links
Under Plugins in the Admin pages, the link for OStatus in the plugin description resolves to some sort of gaming website. Also on the Plugins page, all of the links to status.net are basically dead. It looks like status.net is doing some sort of relaunch, so all of the old links are forwarded to the homepage.
In the /plugins/README.md file, the link for skilledtests.com is dead. The skilledtests.com domain is dead, with just some sort of holding page in its place. Any links to skilledtests.com should be removed.
