Hows this for an idea:

Have a service that monitors gametracker and sends a Text to your phone if certain conditions are met:

1. If the server becomes offline
2. If a certain number of people are in it, over a certain period of time*
3. If the server gets full over a certain period of time*
4. Stops sending Texts if my name is on the list of players

*I set to only text at a certain interval, like once every hour or every 2 hours, etc etc

Basically, I'm not always at my PC, but would like an easy way of knowing if people are in it trying to get it started so I can hop on and play. It would also be nice if it alerted me of server outages as well.

I would pay a small fee for this service.

No matter how "awesome" it sounds it's pretty impossible and expensive.

Allow me to explain you:

Let's say GT actually do this, the providers who allow these options mostly charge 0.04 euros per message.
GT.com have over 2 milion users, and let's just count how much money it would take per hour about this service.

Also some people will abuse servers and restart it, shout down it and etc just to harm the gametracker.

obviously, there should be a grace period when it would stop sending messages. I would only want 1 text send to me like every 30 minutes for a barely active server and maybe 2-3 hours for a more active one.

Obviously, I'm thinking this would be a paid service anyway. You pay for premium, and then you get to subscribe to a certain number of servers for texts getting sent to you.

I would almost settle for emails if it would work better, they go to my phone, but there is normally a delay before I get them.
