I think you misunderstand the problem. I know I can override the formatting. It's just that if I did so, it would invalidate my claim that I have software that lets me call up forum screen names with hotkeys, and replaces the spaces with underscores in forums that allow spaces in names.

In other words, people would know I was needlessly typing out their whole screen name and adding underscores, and it wasn't just some glitchy software.
