I'm going to be creating a page of extensions that are available for BE very soon.  But until then I thought it would be beneficial for me and also for all my readers that are using BlogEngine.net to have an archive of the extensions as I find them on the Internet.  Here will be the first round of posting for everyone to enjoy.

1. Simple BlogEngine.net Download Counter Extension - Al Nyvelt has released his simple counter into the wild. This counter is designed to simply count the downloads of files that are handled by the file handler and not simply by downloading them from the site itself.  This is just a basic one and does not display the counter to the public only once you login do you see the results with the file link.
2. Download Counter Extension - This download counter provides more detailed information in the admin section about the files that were downloaded and by what host.
3. Google Tracker Extension - Chris Blankenship has released a basic Google Analytics tracker extension that simply allows you to insert the tracking id for your account. 
4. Track file downloads - BlogEngine Extension and Control - And not to be outdone Chris Blankenship has also created a file download counter that not only does the file downloads but stores the information into an xml file with the ip address, date and number of times the file was downloaded.  So this brings the count up to 3 so far on the download counter extensions.
5. Updated DotNetKicks button - Chris has also released an updated DotNetKicks extension for us.  It has a couple of improvements over the original one written at Flawless code's website. 
6. Page Load Time - BlogEngine.Net Control - This one is not an extension per se, but is a control for displaying the time that it takes for a page to load within the BlogEngine framework.
7. CommentRelish - BlogEngine.Net Extension - Chris has created an extension based on the Wordpress plugin of the same name.  This extension is developed to increase the readership of your blog by sending out an email to first time commentors on your blog.
8. New BlogEngine.NET Extension - Toolbox - This extension by Danny Douglass allows you to save links and manage them through an admin page on your BE site.
