As a GM of Impervious, we occasionally hold scheduled guild events where it would be extremely helpful if a small section of the event hub can be used as an annoucement board for GMs to use to relay messages to the rest of the guild. That way, if there is an event, message, etc, guildies can log on anytime and see rather than having to refer to a site/forum or through word of mouth.
I can see it being unmanageble if all members are able to contribute so perhaps if its restricted to be a function capable only to GMs and Officers of a guild, and perhaps limited to 1-3 items/notes/notifications under "Guild" tab or "Guild Annoucements" as part of the Event Hub, that would be SO helpful and wonderful :)
Cheers!
