I think we should make a thread for guild rank related privileges.
I say this because I feel that if some member just joins, they may turn out to be one of those people who leave after a guild level up, or they may turn out to be rude. Whatever the case may be, I certainly wouldn't want the items that we have donated to the guild inventory to go to trash members like that(which I hope we do not invite by accident). That is why I think we should only allow people of certain rank to have access to this(perhaps seniors and above? As juniors you gain access to stat and exp boosts).
Saying this, I've come to another conclusion. We should define the requirements as for how to achieve promotions in rank. John has already stated how to become an officer in his thread here.
