AzerothCodex

After completing a Mythic+ dungeon, the addon opens a window displaying the group members.

For each player, you can:

choose a rating from 1 to 5 using gems;

add an optional comment;

click VOTE.
The VOTE button generates an AzerothCodex link containing:

the player's rating;
your character;
your realm;
the region;
the rating;
the comment;
the dungeon;
the key level;
the run time.
If World of Warcraft allows automatic copying, the link is copied to the clipboard. Otherwise, the addon displays a field with the link to be manually copied using CTRL+C.

Then paste the link into your browser to automatically submit the vote to AzerothCodex..
