Digg automated tools

Hey
this week i want to write a guide to owning Digg on my blog. Because i use custom tools to automate some of this stuff that i cant share i want to see options of stuff on the market that is sold to maybe put it as hints to help people use the technique. I tried researching a bit but i cant see any working friendadders or so.

So speaking shortly if you know any kind of working Digg tools please give me url to see what they do.

Thanx

Well i use imacros to automate diggs ,add friends etc
