I‘ve added a few new plugins to my blog lately, thought I’d just give them a quick shout out:
Yet Another Related Posts Plugin
If you view an individual post there’s now a list of 5 other ‘similar’ posts listed at the bottom of the page. I’ve been monitoring how relevant these actually are and it’s seems to pick the posts that I would if I were doing it manualy. Get the plugin here »
Comment to Email Plugin
Often when I recieve I comment on my blog I’m not sure whether i should email the person directly or respond in the comments. Well now I can cover my bases and do both at the same time with the Comment to Email plugin. Also by Nate is a little tool called CSS Text Wrapper, you know how you can flow text within a shape in illustrator, well now you can do it with CSS too!
Get Recent Comments
In the sidebar there’s 2 new sections Recent Comments & Recent Trackbacks displaying a bit more info about who’s talking and where incoming links are from. Get the plugin here »
If you have any top tips of other WordPress plugins I should be using please let me know :)
And finally, I updated my little favicon in a address bar. You’ll only see it animated if you’re using Firefox, so here it is for the rest of us » 
You should try the Disquis or CoComment or intensedebate for comments, it does all the emailing stuff plus lots of other fancy things relating to commenting. I think they’re compatible with gravatars and that too.
