Rearrange Order of Modules and Assign to Positions

Hi,

If you guys had tutorials (youtube clips) showing how to set up or customise profiles that would be v useful!

I'd like to rearrange the order of modules on my profile and news feed and can't work out how to do this. I found the Module Positions support page (http://stackideas.com/docs/easysocial/administrators/module-positions) but this doesn't explain it.

The default setup includes a bunch of positions:
eg. Position: es-general-top [ Style: xhtml outline]
... but it doesn't seem like modules are currently assigned to these positions.

How do I rearrange (or unpublish) these existing modules on profiles or ES home pages or do I need to set up new ones and then rearrange them?

Cheers

David
