I think a spoiler bbcode tag would be nice to have here.
Something like this.

whats the point anyway? the only threads that do contain spoilers are the ones about specific f1 races (and a few other classes) that pop uo every now and then
those would be full of spoiler tags (annoying) and anyone who opens these after the race will expect them to be full of spoilers anyway

Quote from AndroidXP :

Spoiler - click to reveal

You could just fake it like that

Mmm, yeah ok. That kinda works too.

Movies, TV shows (Top Gear eg.), sports events to name a few others.
