I haven't seen this suggested on the forum yet, but this might even fall into the category of "low-hanging fruit."

In order to better keep track of guild members, might it not be useful for there to be a rank like "Inactive Member" or some such? Thus players who haven't been on for a month or so wouldn't have to be kicked out of the guild, but the actual number of "active" members would be easily definable...

Or, even, the ability for guild commanders to set up the ranks as they see fit.. but that might be fruit which is not quite so low-hanging...

My suggestion was shorter ;)

sounds great to me. would also be nice to have more people that can give guild invites...
