[arch-multilib] Question about user contributed multilib packages

Hello, I am somewhat new to Linux and have been using Arch for about 4 months now. I was excited to see that Arch adopted a multilib approach to 32/64-bit software packages. I decided this weekend to try and get Neverwinter Nights running on Arch64 and successfully did it. I had to create some lib32 packages in the process that were not available in the multilib repository. My question is, is there a process to submit multilib packages or do i just upload them to the AUR and wait for them to make their way to community then on to multilib? That being said the packages that I have created are: lib32-elfutils, lib32-libmikmod lib32-sdl_mixer and lib32-smpeg. Thanks for the help, JD
