To BB or not to BB?

I've been going cross-eyed for the last few millenia  hours trying to work out how I can start building a resources link on my journal (for example, I've just downloaded some textures that I'll use later to make some icons and I'd like to be able to put a link to the clever sausage who made them somewhere!)

I've seen resources links on other journals but I can't for the life of me find a way to put one on mine ... maybe its the theme I'm using, I don't know.  Same for loading my fic on LJ ... no idea!  (I'm guessing, perhaps wrongly, it's the same method?)

Can someone point me in the direction of a tutorial or something to help me do these things?  I'd really appreciate it.

Cheers
Me
