starting this day please do not use embedded youtube (or other such)-videos as your signature

people who read this site from work are most likely to be behind firewall which will quite often block viewing such posts/forums
(as reported: videos in signatures -post)
admins will remove all such signatures

adding a link to video shouldn't cause any such problems
(embedding a video in posts can obviously cause firewalls block sites but can be still labeled as minor nuisance and no bans for that)

so thats why i can't check the forums properly from my work... MAKE IT STOP!
