SourceForge provides some simple to use ways to contact me:

• IP Monitor forum - Comments, Help, etc.

If you think there is something which is not working fine with IP Monitor, or you've thought of some way to improve the application or you are just bored :) don't hesitate in posting there. I can't assure you I'll answer it immediately but I'll do my best.
