I am in the process of writing an application that can be offered to your users, if you are not listed, that will display all servers that use gun.fllistserver.com
Note, server admins will need to make sure the following line is uncommented in their freelancer.ini file on their server host machine.
Hostname = gun.fllistserver.com
I plan to offer this as a download for my users and thought other admins who aren't listed might find it of use. I will post a link to it when it is done.
