I have made a section on the wiki for those who would like to make a page for their guild or group. Just search "Organizations and Guilds". If your organization is big/important, put a link to it on the front page in the appropriate box, as well. I will alphabetize the groups once more make a page. Please use proper grammar and I would request you don't make unnecessary pages if your guild is very small and has no lore/info.
Thank you, Petyr.
