Due to a lack of discussion in our classic forum layout I've decided to go ahead and re-enable the newer, message wall inspired, forums. Using this forum type we can highlight discussions wiki-wide and hopefully can bring more attention to discussions that require community input. In addition to highlighting wiki issues I hope that re-enabling this kind of forum will help promote general discussion, especially regarding the game, without limiting talk to specific champion pages or blogs.
The reason we disabled this type of forum before was that it was tied to a buggy message wall feature (I've also re-enabled message walls because of numerous bug fixes that have happened since the last time we had them enabled). If someone feels a discussion requires the format of the old forums they are more than welcome to create a page in the style of them and link it using the new forum.
As always this is something that is something that is up for discussion. Just because I enabled them does not mean that I am totally opposed to disabling them again.
