Chosing language homepage?

[Goodman_2020]

Hi,

I want to install 2 vBulletin forum.
One will be in english, one will be in french.
I would also like to install vBadvanced for both of the forums.

www.mywebsite/fr/vbadvancedhomepage (will be the homepage of vbadvanced. "Fr" is for "french" and the name of vbadvancedhomepage wont be lke that, it's jsut to explain what i want.)
www.mywebsite/en/vbadvancedhomepage (will be the homepage of vbadvanced. "En" is for "english" and the name of vbadvancedhomepage wont be lke that, it's jsut to explain what i want.)

Like you see i would like to install 2 forum with vbadvanced for each, but one the same domain name. 1) There's no problem for that??

2) second question: as default home page (the one we reach writing www.mywebsite.com) i would like a page with 2 different flags, and clicking on it, you are redirected on the good vbadvanced homepage (and then so forum)
Is it possible to do that?

Thx for the help
