Organic Groups issue's after installation

Hi,

Newbie Alert!

I've installed Drupal and all is well. I also installed Organic Groups and the pre-requisite modules and enabled them all. I've also set the permissions for any logged in user to be able to use all the modules / features.

I've read as much as I can.

For the life of me, I can't find or work out how to create a new group. I can see listings of groups already created (which there are none, of course).

Ive tried going direct to various combinations like

/?q=node/add/og

or

/?q=node/og/add

and nothing works.

Please help!!!

thanks
