Please note these are daemons, and as such, dont pop up with any frilly windows for you to play with. If you dont know what a daemon is, then the chances are you dont need one.
Drop the daemon into Boot:Choices.Tasks where it will load upon boot.
Some daemons (IdentD etc) have configurable options (where you edit a variable in the code). If you dont know what this means then again, you dont need it.
