Forums / Cotonti / Support / Simple Question

Hello,

I don't know if I'm just blind or what, but I can't find one thing. How can I manage blocks in Cotonti? On the right side of my website (using nemesis theme) I have default blocks:

*Admin

*Polls

*Tags

*Online

Where can I manage it? move them up o down, delete and create new ones (you know what I mean). I can't find it anywhere in administration panel.

Also, I can't manage top main navigation. I have *Home *Forums *News *RSS *Search and I don't know how to delete them or add new ones.

I'm far from professional web developer so please forgive me for this question :)

Thank you.
