My suggestion - that dues for being in the guild in WoW be enacted based on some basic random formula that ensure higher levels pay more than lower levels.
Then...whenever someone creates their FIRST Alliance (because the Horde are evil, vile and selfish creatures you know) PC, and joins the GWJ guild, that one PC gets a free tabard thingie (1gp costs) to wear proudly. The tabard would be bought from dues paid in, and given to the members first PC to look uber cool!!!
Hey...that's my thoughts and I'm sticking to them!
