Discord has a straightforward URL format that isn't immediately obvious from the style of the links:
https://discord.com/channels/[server numeric id or "@me" for DMs]/[channel numeric id]/[message id]
It would be nice if there was a Mediawiki template that this wiki and others in Fandom could use to reference such links, prettifying them so they are easier to read (so it might look something like "by Foobar#1337 in #cool-channel on July 29, 2021" instead of the opaque slug above). The semantic details would be supplied as parameters by the user, since I don't think there's a way to query the Discord API for this on-the-fly. If/once a template exists, it is easily copied from wiki to wiki (according to [[w:c:help:templates]]).
