A few site updates

I have done some work on the site today, most of which you won't care about, but I thought that I would mention them so I can get feedback where required. I won't bore you with the smaller technical things, but will mention the larger things you may actually notice.

Starting from the least important and working up...

• The different categories on the homepage now link to their respective category pages. Most of them had a link elsewhere, but the main one that didn't was the site news (I know - your favorite section!) so now you can read all the really interesting news updates you missed the first time around.
• I have added the dofollow plugin. This borders on the technical but what it means for you is that when you comment on the site and leave your site url it will be posted for all to see WITHOUT the nofollow property. This means Google, and other search engines, will follow the link, hopefully improving your standing on the web - so get commenting (spamming will still be blocked - we don't like spammers!)
• Finally I have added a subscribe to comments feature. This is a small experiment as I've never used anything like this before, but essentially it lets you get email alerts for comments, so if there is a topic that interests you, then you can get updated when new people post something. I think I will try adding this to my personal website as well.
