Unmaintained - AssociationMc
Minecraft Account Association
For a MineCraft forum, it's nice to know player names. If someone doesn't have the same username as their forum name, or even if they have multiple accounts, it can get confusing. Plus, it shouldn't require too much work due to it already being made :)
Pros:
- Good for changing forum names (no need to verify in-game)
- Support for multiple usernames
- Verify using minecraft.net directly
- You can verify weather or not you are banned in-game, as long as you have a forums account.
- Add-on to Xenforo, no need to create something brand new.
Cons:
- Is a little glitchy (sometimes verification doesn't work first time).
- Site goes down/verification doesn't work in some browsers at times.
To verify it's quite simple, you type in your username, pick an associator password (can be anything) and then verify you own the account by changing your skin, directly on minecraft.net, so it is completely safe.

Here's how it looks, under your name. Obviously the red is the user names to your account(s). Up to 5 can be shown at once (you can choose which 5).

-- Look under "Password" to the bottom left!

Thanks for considering! ;)I can't add this in:
