I'm just getting into writing my own modules, and need to know the code to determine if the currently logged in user had admin prevelidge.  Can someone help me out?  Thanks!

 Do you mean edit privleges or is in the Administrator role?

To check the Administrator role, use
UserInfo.IsInRole("Administator")
[check the spelling on the role name to be sure]

If you want to see if they have edit access to your module, use
IsEditable

It is also possible to add your own permissions for the module. Check the UDT (now Lists and forms) for an example of additional permissions. Digging in their source code also gives a nice set up for how to implement it. I use a modified version of their setup for my module template. (You better be using a good method UDT Team, *shakes fist*).
