Hi ..
Two things first it would be really helpful and fun if in guild there could be a practice area for pvp, and or training and explaining fight techniques to other guild members, giving members an opportunity to strengthen comaroderie and skills, it would be worth the plat and be a added bonus to recruiting new members.

The second suggestion is just simple Fun, I would love to decorate my guild hall with seasonal items. They could be rented just like the Halloween costumes are being rented. oh I really hope u do both but honest I'd love to deck the halls at Xmas.
