  I am getting the following error and I believe it is related to the Medium Trust Security Issue.  I have done some research, but I would like to understand exactly what I need to do to resolve this.
  
  My site contains a Home page, Blog Page, and two custom pages - Create Blog Post and Update Blog Post.  Both the custom pages have my own user defined controls that use the radEditor.  The users can create a blog post and update it.  They can also upload images to the posting.
  
  Here are some initial questions?
  
  1 - I need to make this a secure site.  Will this work?
  2 - Will my users be able to use my user control to create and update blog posts?
  3 - Will my users be able to upload images to via the radEditor?
  4 - Where do you actually set the trust level to medium?  One blog mentions doing this before updating the web config with other changes.
  5 - Are there hosting providers that allow for full trust?  I'm thinking that discountasp might, but do they offer SSL?

  Hi Randy Bauer,
  
  The problem comes from the security trust level that is set by your host. Most probably you are trying to run the website in full trust since your host supports Medium trust. This post describes how to configure your website in Medium trust and which features you have to disable.
  
  A good host is discountasp.net which supports full trust.
