NSider's one of many forums that has members using coloured text, so, even if this wasn't his first forum, it'd be highly improbable- if not impossible- to determine which forum he was on beforehand. I was a regular on PE2k once, and the number of people using coloured text was a surprisingly high ratio compared to those who didn't; even many mods, gmods, and admins iirc used it. I assume that quite a few other forums are similiar in their treatment of coloured text and its usage.
