CMS Made Simple Forums

I'm new to this and could really use some help. I'm running 1.7 "Cape Verde" and want to upgrade. First question - do I need to upgrade to the "next" update and then upgrade again, etc. or can I go right to the most current upgrade?
My second question concerns including a YouTube video under our events page. I don't have the "embed" icon on my CMS screen, so I'm having a heck of a time doing anything with the YouTube embed link. I'm hoping that upgrading the version of CMS I'm using will help with this. Thoughts?
Thank you!

First you need to read the upgrade page here http://docs1.cmsmadesimple.org/...

As far as youtube embed there are a few ways to do it, the best way is to paste into a content block w/o the editor enabled so it doesn't change any of the code, search the forum for it...

My opinion on Youtube code:
