When you are in more then one guild, and use layouts/keys to make your posts look better you might have more then one page you have to be on to copy and paste. This guild was made so you can keep all of your characters in one topic so you can copy and paste all of your layouts without having to use multiple tabs for them.
If you are scared of character theft, i'm sorry but there is few things I can do about that other then lock the topic so only the guild leader/crew/vice captains/ Can see it but that only helps us, and then each of us may try to thieve as well.
But to reassure you, your fellow guild members are not cowardly thieves who will creep your layouts for a good one, so please feel free to help yourself to a hassle free character page.
