Agree, but it's their choice to look like a childish person, right?
However, I'm not sure if anyone is so stupid to do this...
I don't think the colors/fonts/sizes are for special occasions, I've seen alot of Forums who have got this system already, and it works out perfectly.
I think we should atleast give it a try, it's always nice to pimp up the Forums a bit!
And let's say if there are people abusing the system a rule can be made about it and warnings/infractions will be given?
