Just before NOVA began to implode, there was a wiki floating about focused solely on all things eikaiwa. Sadly, it went offline before NOVA collapsed and has been offline for at least a year.
The Eikaiwa Wiki is the product of long-time LJ reader Novawhiz, and I am happy to say that he has graciously allowed LetsJapan to host it.
Novawhiz has spent a fair amount of time in getting the wiki back up and running, but since it has been offline for a while, some of the content may be out of date or in need of expanding. This is where you, the reader, come in.
