I’ve made a website dedicated to everything Sangheili. 
It has built in Forums too so that the community can communicate much more freely with each other. You can sign up, set up a profile, make posts etc. So ye, it can be a Sanctuary of sorts for us Elite nurds. Anyhow, the website is here.
Thanks for reading. :v Again, the site: Sangayri. (Sangheili in Sangheili.)
