Im new to zonealarm, and just wanted to know what most of you that use it on Mirc set the Restrictions to??

For example, when I first connected it asked me if I wanted to allow Mirc access to the Internet.. Well obviously this one had to be answered with YES. But its the second question I am unsure of whether I need it or not??? It asked me if I wanted to allow Mirc access to act as a server?? (or something similar to that).. I tried using Mirc with it enable and disabled and noticed no difference.. What exactly is that Server option in regards to??

I want to say it is to allow me to send files to others?? But again, Im not really sure.. Can anyone shed some light on this subject for me????
