###End Of Life proposal:
We have many EOL questions, currently considered off-topic. So I propose we have a custom off-topic reason for them, we should include a link to a question that shows them how to update Ubuntu - Possibly a link to the EOL date list for when versions are no longer supported (maybe even the question that tells them how to add archived repositories)
Qusesions with custom closed votes for EOL so far:
http://askubuntu.com/questions/312850/how-to-install-mkvmerge-gui-in-ubuntu-11-04
http://askubuntu.com/questions/312713/install-virtualbox-guest-additions-feisty-fawn
Possible wording, feel free to improve/edit/comment on so we can get a good version of this:
Questions about End of Life Ubuntu Releases are not supported here and are therefore off-topic. longer supported.
