this whole relog-between-servers-and-change-position thing is a pretty serious topic. a friend just got shot in the back after defending my dead corpse, cause some friend of the other killed guy logged to another server, run into the house behind our position, relogged and shot him. this audio signal could be a first step into the right direction to solve this problem. a waiting queue of maybe 10 minutes before you can relog to the SAME server you played before could be a good addition to prevent at least instant relogging.
