Hi
Recently I have removed loads of old doorway pages from my site - very spammy with repeating text etc. Horrible stuff. To my surprise they all have a PR of 2. They are on the server but not linked into the site. I only decided to unlink them from my site a few weeks ago. Lets just I've been doing this SEO thing quite slowly in my own time but there you go.

I am surprised they were page ranked at all so I'm not too sure what to do with them now. I suppose I can write original content for them but should I relink them before starting this or are they quite useless?

thanks for bothering to even read this daft question
