install AIAB now!
it gets you up and running with a nice looking interface with no fuss & no bother.
Once you've got the bits you need then you can start tweaking. But AIAB's pretty good staright from the off; let's be honest, there's no point re-inventing the wheel every time you need one, is there?
If you like a blank sheet, then go for it. But with AIAB you can be using your Amiga a lot quicker....
