Seriously now Benderboy123:
Peel won't make another board just for Alien languages. As TLI pointed out, some Peelers proposed to create a new board for music and video games, and it was denied.
All Alien-laguage sightings have been discovered and because of Futurama beeing cancelled, there won't be any new ones.
Also, as Teral already stated in another thread, there are too few sightings of AL3 to decode it.
I think the writers have planned to use it more often, but as I alrady said, Futurama is cancelled.
Go through the Re-checked/Weird Scenes Board (use the search-function) you'll find enough threads about Alien Languages there.
Beside that, the field of Alien Languages is just too small to deserve a whole board of it's own.
