Automounting external USB so as not required by root

[Ferindo Middleton Jr]

I have an external USB drive. For some reason, it is not accessible to 
anyone using the machine unless root mounts it first. Default 
configuration of my system doesn't allow apparently anyone else to mount 
the drive but root. How do I change this so that device is mounted 
automatically and is accessible to anyone using the system by default?
