By default "nofollow" is not added to the comment user URLs in Blog Engine .NET. 

You probably want to use "nofollow", because you do not necessarily trust the links being added by your visitors, and you do not want to lose page rank by linking to potentially bad sites.

This is very easy to do with Blog Engine .NET version 1.5.  Simply follow the steps:

1. Open the CommentView.ascx file in your theme directory (root\themes\).

3. Change "a href=\" to "a rel=\"nofollow\" href=\"

4. Save the file, and you're done! 

Refresh the page, take a look at the source, and you see the issue is fixed:

Recently I wrote a .net console script to automate some stuff in Excel and part of the script includes uploading all of the contents of a given directory to a SharePoint document library.  After moving the script to production it did not work. Turns out that you need to have the WebClient service enabled. This service is disabled by default in Server 2003 so you will need to set it to Automatic or Manual and then start the service.

After starting the WebClient service you can access the SharePoint library like: \\sharepoint\site1\documentlibrary
