Now if I might suggest something, perhaps linking the little card store so much with the guild might just be a bad idea. You could even change the store's subfourm to a Exchange subfourm for the guild. But what do I know, I've only help run a few guilds.
The reason that we did that is because essentially the things people notice in signatures is what relates to their interests. We have had many people join because of these card-based signatures, and they were done for free by DeckMaster/DarthSpanky for the guild, so he was free to advertise in them. We have a symbiotic relationship with him as many people who come to this forum are also interested in getting their own personal cards made.
Thanks for your opinion though - I'm sure if you've thought it, other people have too.
