Custom links in admin theme

[avendi]

Hi,

I'm a designer from Germany, not a programmer. So I need your help.
I want to add a custom block with links on the home page of my admin theme.
So if the current admin hasn't got permission to visit the section, link would not be displayed.
If he has got permission, link would be displayed.

I think this must be a function or smth like that:


If (has permission)
-- show my link
else
-- show nothing

It's not so hard, I think. Thx a lot.
