It’s also the main organization tool for “groups”. I have tried to migrate mine to other platforms with no success.
And also the biggest online classifieds marketplace for trading goods. Even though it’s a fucking awful experience and simply ignores any filters you give it. If you want to actually sell your stuff, or sell it for market value, without shipping, you just have to use it.
