Welcome to MitchelSellers.com, this is my personal blog/commentary site and is in no way, shape or form affiliated with my employer.  On this site you will find a few key pieces of information.  In the Blogs section you will find technical articles focused around .NET Development, mostly C# content articles and with an empasis on ASP.NET and DotNetNuke implementations.  If you are looking for technical assistance the Forums section is a great location to ask for specific help, I try to respond to all forum postings as quickly as possible.

For those looking to interact with me in a more direct route, such as Consulting or for a Speaking Engagement, these sections of the site will provide you the needed information to get in contact with me.  If you are looking for more information on my career and experience you may review an online copy of my Resume, or Contact me for more information.

Lastly for those attending any classes that I teach for the Business Information Systems department of Des Moines Area Community College (DMACC) you can view the Courses section to download any course specific documents.

Development and Test DotNetNuke Installations and Search Engines by Mitchel Sellers
It is quite often that when working on a new version of a site that you will have a development, test, upgrade copy of the site that might be around for a while.  It is also possible that if you are working for a third-party that you might stage client sites on your server for a period of time before go-live.  At first glance this all seems common place and not something that you would be concerned about.  However, that is not the case.  Search engines have become overly aggressive in indexing sites, including those that have no direct back links but have been e-mailed to individuals or similar processes. In this post I'll discuss some important considerations when working with these "non-production" installations to help you ensure that search engines will NOT index the content and cause confusion.

DotNetNuke Login and Auto Complete - How to Cope by Mitchel Sellers
Recently I have been getting a lot of questions regarding the DotNetNuke login and why when you go to login that "auto complete" is disabled on the username/password fields.  The typical follow-up question to that is "how can I change that behavior".  So after answering this question individually around 5-6 times I though it would be best to get this out here, at least my opinion on the issue.

Windows Updates, Monitoring, and ASP.NET...Oops! by Mitchel Sellers
For those of you that are regular readers of this blog you will know that outages of the site are very, very rare with the past year showing almost 99.9% up time.  Well if you were around here this AM you will know that the record for up time was killed, with the sites being down almost 10 hours today.  In this post I'll talk a little about my experience with this as I know a number of other people across the world have experienced similar issues this morning based on my conversations with a few of them.
