I updated this thread a bit:
I replaced the youtube links with embedded videos using the [youtube][/youtube] tags.
The third video, which was a tutorial about how to make a post in forums, apparently has been removed by it's owner, so I replaced it with another useful tutorial on how you can make a post in forums.
I also changed the FAQ url, the one before was from our old forums, which doesn't work anymore, so I replaced it with our new FAQ url. ^~^
