Hi Emaynard,

What I do is a very simple approach.
1. Copy the "Register.aspx" plus its code behind to a new folder in "DesktopModules" folder.

2. Create a new user control for new fields (textboxes, dropdownlists, etc.) those are you want to add. Put this new user control file inside the new folder you just created as well.

3. Create a class for this new user control (you can follow "Address.vb" as a sample). In my case this class file resides in "App_Code" folder

4. This new added fields should be stored in new separate table in the database and using some new stored procedures to store their values. So make sure you create a new table with some info so the data could be retrieve/change for related user - I put "PortalId" and "UserId" in this new table.

This only one of many ways to do this. But with this way I can make sure that I never touch the core/original codes.

Please feel free to do it with your creative ways. As my level of programming also still mediocre :P
