I would like to display the login link only, if the user is not 
authenticated, and not a robot.

I am not clear on the exact sytax though concerning variables and 
combining variables. I tried this
(:if ! auth edit && ! enabled IsRobotAgent 
:)[[{$Name}?action=login|Login]](:ifend:)

to no avail. I also tried $IsRobotAgent and {$IsRobotAgent}
