I've tried everything I know to try to get "Multi-Colored" usernames, but can't figure out a way to achieve this without having to use an image :/
I know there's a Javascript to make your username have each character a completely random color, but I need it to where I can pick the specific colors. What I'm trying to achieve is "DevilsParada89"
Help is appreciated!
Well Javascript isn't an ideal solution since it would require clients to have it enabled; this really should be done server side.
If it's just one username, stick it in a custom group and make the name formatting the appropriate HTML.
If it's a range of usernames, well, that'll require some coding...
That's my problem, there's only so much it'll actually save before it cuts it off :/
Edit your database: change the namestyle column of mybb_usergroups - by default, the max length is 200, so change it to something large enough to hold the name.
If you get an error asking you to put {username} in there, you can just wrap comment tags around it.
Thank you! Finally got it thanks to you! No one else on the MyBB Community Forums seemed to know, or they said it was impossible. Thanks again

One last question. Before I changed it, I had an image for his username which looks practically the same, except it was an image. Whenever I go to a thread where he's posted, his name is still the image, but everywhere else it's actual text. Anyway to fix this?
Do you mean you had an <img> tag in the username style for the group?
If so, MyBB doesn't use username styles everywhere, so in some places (such as last post) it'll display the plaintext version. Do you want the image to be used in these places?
No, I had the <img> tag in the username style for the group previously. But now I've changed it, however, in the post area, in the actual thread(postbit I think is what it's called), it's still showing the old username image I had, instead of the new text.
Either your user is a part of multiple groups or you did the modification into the postbit template itself.
Fixed the problem. Had an old plugin active I never deactivated.
