You Tube help

hi guys, I just posted this in completely the wrong place and I can't delete it, so apologies for that! Maybe a mod will get rid of the other thread ( it's in freelance writing of all places! I feel like such a dope!)

Anyhoo, hope this is now the right forum, if not apologies again!

I'm trying to post youtube videos of a talk I gave at the CBI Summer conference in Dublin this year. The talk is approx 46 minutes long, so I cut the video into five sections. Is there a way to make certain that a person watching one section can automatically go to the next? I know very little about youtube ( or indeed the internets!) and this doesn't seem to be covered in the help sections (though I may just not know what to ask!)

Thanks Wayne, alleycat gave me a bit of help on the duplicate thread http://absolutewrite.com/forums/showthread.php?p=3988998#post3988998

Sorry about the duplicates!
