My wordpress site has gone mad! help!

I'm no programming expert, tbh I am more of a beginner at basic wordpress sites, but I've set a few up before and so agreed to help set one up for my brother about a game he loves over on Chaotic TCG Masters

thought I'd got it bang on. Not great design but it was what he was looking for so was very happy about that... only now I look a bit closer it seems somethings gone wrong. using my SEO tools thingy I can see every single link, including internal ones and those in the forum, are 'no follow'

I hunted through the theme to see if I could see why and couldnt find anything (using Music Magazine Free Wordpress Theme Design theme) and so I tried changing back to the default theme just to check - and that was completely nofollow as well.

I can't work out how this happened for love nor money - the demo for the theme is all dofollow, and thats how I want it!

It's not a plugin to my knowledge - I am using

Akismet
All in one SEO pack
Google analyticator
Google XML sitemaps
Polldaddy polls
Sociable
What would seth godin do
Why do work adsense
Yet another related posts plugin

So as you can see I need help. Obviously my brother is unlikely to care but from my own point of view it's driving me nuts not being able to work it out - I actually quite liked the theme and would be tempted to use it in my own efforts but not if I am going to repeatedly do this

has anyone any idea how to work around it?
