users want to fully communicate with others in ts3
server admins want to grant access to users by adding them to server groups
server admins want to remove invalid users from all groups
they all want it in fast and automatic manner
decision about to which group users should be added or when they should be removed
  is based on information about their eve characters

service receives a http request from user to create a time limited registration record
the request contains a cookie with information about user's eve character(name, id, 
  corporation ticker, alliance ticker)
user connects to a ts3 server and is automatically added to a proper server group
service periodically contacts validation server and removes from server groups those users
  who are marked as invalid by validation server
