 +===== Network rules =====

 +Summary of the most important stuff:
 +  * Only registered devices may be connected.
 +  * This is an academic network, meaning that the primary uses are research, education and similar. Commercial activities are disallowed.
 +  * Illegal distribution of copyrighted works is strictly prohibited (BitTorrent, DC++, web, the means do not really matter). Illegal behavior in general may be prosecuted.
 +  * The users are responsible for their devices, both for the contents and the security against misuse.
 +  * The user must not //by any means// share the connection to the third parties. This is why //we will not connect your routers//.
