Wow Richard! That was a really great post! I've never actually used any of the Paint.NET plugins for some reason but I am now!
Thanks for putting that together Richard, I just linked to it from an article on the homepage. 
Thanks for the comments but one of reasons why I did it was I noticed you write on -
Basic Paint.Net Features ArticleNext week we’ll get into some of the more advanced things that you can do with Paint.NET.
I though to my self i should do a Plugins post like yours in case people want to expand Paint.Net but then things happen in real life like they do and this morning I had some time to kill so sat down and started writing up the post/guide and I tried write about and include screenshots on the plugins which I had used personally and also though of the plugins which are a bit different from just doing small minor changes to the program
By the time I had finished writing up the guide I when and got some lunch and came back I found your write about creating a Web 2.0 Logo using Paint.Net. First though was lucky it was not on Plugins

Glad you liked the post. Hopefully I be able write more guides in the near future but more focused on a certain addon or some thing entirely new
