You have a huge number of sites that need similar changes. Don’t worry nuke can do that for you. Apart from the usual control over content that using a CMS gives you, DotNetNuke gives you control over multiple sites from just one interface. This is done by cumulating sites into groups.
So you have all the control to make changes to all your websites from one area.
We at Zenesys will make this happen.
Discuss with the developers the next iteration. Build up your thoughts. The developers will help you understand the requirements.
Approve the design for the developers and sit back as they develop your product.
The final product will go under recurrent testing to provide you with a product of assured quality.
