There is now an account set up for donations to the Guild. The username is HollywoodUndeadGuild. I find that it is easier to keep track of the donations that are for the Guild or for the Hockey Masks. If you would like to donate to the Guild, send a trade marked as Guild Donation. If you would like to donate to the Guild for a Hockey Mask, send a trade marked as Hockey Mask Donation.
The account username is HollywoodUndeadGuild.
Oh and feel free to add the account.
