What IMPORT should i use for the SECURITY updates for BRApi

Not sure why my original comment disappeared...

But agree with MarcusH​.  Putting it all together would look something like this (please add logging during development to demystify)

Dim objList As List(Of Group) = BRApi.Security.Admin.GetGroups(si)

For Each grp As Group In objList

	If grp.Name.StartsWith("QA_") Then
		
		api.LogMessage("Log Group Names that start with QA_", grp.Name)
	
	End If	
	
Next

Also, please be careful working with different object types.  Original code retrieved an object of type GroupInfo but was attempting to loop on MemberInfo (which was not declared).
