Thank you very much
I will have a good look at this as it seems to be more of what I was trying to find.
We have a lot of custom plugins in our current CMS which would need to be migrated accross and I just need a clean way to migrate existing and build new modules on our own sites. I see there is also an advanced section that uses Ajax which is something we will use a lot in our modules

I will need to pacakage some modules for later use but for the moment I need a way to get us up and running asap.
Heres hoping Stuart

Hi II followed your super simple module example and despite getting the Error  It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level.  This error can be caused by a virtual directory not being configured as an application in IIS. E:\dotnetnuke\Dotnetnuke\web.config 113 when I built the page. I could not find any extra web.configs???.
I was still able to to get the module into my DNN7 site following your advice. However, when I first added the module I could see all the account details laid  out in the gridview and the search tool worked fine while in the edit page mode.
As soon as I switched to layout mode just a blank page and module title, this happend with my previous attempt with a product module..Now it may be that I am not catching on to how these modules work but I assumed that the web user would be able to see and use it. must have configured something wrong?
Any pointers to both errors
