I have a very modestly sized signature that I align using ------ characters that are white colored, to get things centered where I want them. I was almost done but just wanted to add a few more ------'s to align the Next Weigh-In line to the center of my two tickers... my signature wouldn't get any LONGER, I'd just be centering one of the lines. But it won't let me center it all the way, saying after a certain point that my signature is too long. But... it's not that long! T_T Is there anything I can do? It doesn't look good and is bugging me.
I counted it out... I need exactly 11 more characters to be able to get it centered right. >.<

I think it looks just fine the way it is now.

I would suggest getting rid of the white characters you are using to center it and use the center tags around the sentence instead. Everyone has different size browsers, resolutions, etc that will change how they see your signature, so using white characters is only going to center it for your view but probably not everyone's view. If you use the center tags, it will center for everyone.

These are the centre tags:
You may already know that but...
