Hi! I made my username on the forums 4 years ago. Naturally, I would like to change it to the username I use now. (iiPidgin, my ign.) If anyone could tell me how to do this, it would be greatly appreciated. Thanks, iiPidgin.
Log into the lobby on the server, or if that doesn’t work, into the Adventure server, and it should update
The step above is done if "snappy2007" was a previous username of your current Minecraft account (meaning the account that used to be named "snappy2007" needs to now be "iiPidgin". If "iiPidgin" is a separate account, you may need to be re-whitelisted in-game. If it is the exact same account as before, only with a name change, you don't need to worry about what I first said, and your forums name can match with your account name by taking the step which @BetaStrawberry said above my post.
I took care of this for you. As noted above, future name changes will automatically update by visiting the lobby.
