Well at the moment it lists every person who has ever set up a character on the website, ex members, non members etc.
I would just like to be able to filter it so that only FULL GUILD members show in the list.
It takes some management. You can do 2 things. Go in an manually delete or mark those that are not in guild as NOT IN GUILD and they will no longer show up. They easiest thing to do is to use GRSS. It takes a guild snapshot. Then go to
Admin > Characters and Accounts > Roster Uploader. This is where you upload the GRSS Guild Snapshot. It will give you options of what to do with those that show up in the roster on the website but not in the roster of the guild in game. I think the default is to mark them as Not in Guild.
