Belle practice with the tags (Guild Black) etc is broken,

can we not have tags that are private to us? (ie need a password to join) as Bello were trying to practice and just random 'noobs' kept joining the practice tags and ruining it,

is this possible? im generally happy with the five guild system, but the state of guild sparring and the guild spar rooms atm is horrid,

i enjoy the update, but please can we fix this?
