Im not sure I understand,
You mean you want to enter:
and have the server ping them every X seconds? and display up/down on the forum header?
I would assume you want support for multiple hosts, right?
@bentael Right, like you could name a service, so for example:
Service Name: "Super Duper Web Server"
Server Host or IP: 127.0.0.1
Service Port: 80
Icon Colour (service up): Icon Colour (service down)
Check frequency (seconds): 60
Then the icon you select would show up in the header in the colour that relates to it's status. When you mouseover it would show service name.
I could see this being useful for webhosts who have forums - they could list their webservers in the header, or game server hosts, game clan websites, little things like that. Was just a random idea I had.
