As of now, I've simply been using the debian and linux-mint tags together, but since the linux-mint description reads:
Linux Mint is a Linux distribution closely based on Ubuntu
and LMDE doesn't meet this description (it's based on frozen snapshots of Debian Testing, I believe), what course of action should I take?
Update the tag wiki (or suggest it be updated since I don't have the reputation)
Continue using debian and linux-mint together
Create a new lmde tag or something similar
etc.
