I think its a bit silly that a forum centred around pc parts and pc gaming have such a small file size rule on signatures so that no one can even have a steam signature. They are a great way of seeing what games others are playing and a link to their steam profile. They abide by the size rules but occasionally the last game you played might up the size of the image file and the signature will be removed. So now there are hardly any people left using them, which I think is a shame.
The no swearing in videos rule I think is pointless and a hindrance in the PC games section. The amount of times I see people wanting to post up a video to help someone else but they can't because there is a swear word in it.. I agree there shouldn't be swearing allowed in posts, but when there's one hidden away in the middle of a video I think a bit of leniency by the mods would be good.
