@rado1100 - The only way i can think of obtaining the amount of toricredits in ones account, would be a command like... !tc <accountname> <pass> which wouldnt be very good cuz everyone would be able to see your pass..
Now if you could private message the bot, it might not be THAT big of problem.
A month or 2 ago i wrote a forum posting bot, which can login to a forum and make posts. Now i could modify it to go to the torishop page, and look for your tc amount.. but this is probably the worst way to do it.
Now if there was a list of the amount of credits everyone has like i know there is these
http://toribash.com/dump/belts.php
http://toribash.com/dump/store.php
So IF there was one for toricredits which stores a username and the amount of credits beside it.. Then it would be really easy to do.
And as far as running lan servers goes, some older versions of toribash come with a server daemon. (2.8 is the last version to have the server i THINK)
And you need a registration key for it as well.
