Salut Jerome et bienvenu!! Siegfrieddo, beta player here.
I suppose you and your crew must be really overwhelmed by all this! You probably know it, but let me reinforce it, you guys have a jewel in your hands. An awesome community, tons of great material and a great forum - courtesy of the amazingly talented previous caretakers of the site and the people that keeps it alive - the community. Please don't forget that. Keep the site clean, fast, bug-free an up-to-date but more important than that (to me at least): be a cool and participating boss or give us some cool people for that - community managers).
I'll keep my suggestions coming as I remember them. The 1st one that comes to mind dates from an ancient forum I used to visit daily in my early teens (don't even remember the theme...): foreign languages sub-forum. I loved that so much because we could form smaller, cosier, friendlier communities speaking our own language. I usually don't have the opportunity to discuss HS in my language (PT), nor do I know many players from my country. A foreign language sub-forum could do that. I'll actually consider opening a Thread on that asking for people's opinions, so the subject remains more visible.
That's it for now and again, bonnes chances!
