Not sure if these have been suggested yet, but I was just thinking that it'd be useful to have a blank board to write on for guildmasters/officers to help write charters, announce guild events/schedule guild PVPs, runs, etc. I could definitely see the use for this, and it could maybe be another tab on the news/mail/updates Spiral Uplink page. That would really cut down on the out-of-SK contact needed and help guilds be more organized.
It'd also be useful to have an option to write a mail to all guild members to announce changes and such. Maybe restricted to GMs only or something to prevent spam.
Just some food for thought (:
