Let’s Say I have 3 different communities with 3 different languages one of them is RTL Arabic. can I install Discourse app like this
Would they have same topics (translation?) Or the forums are supposed to be independent?
They are independent. I saw Mozilla community it’s multi language community but Arabic categories not RTL
If these are independent, I’d suggest setting up multisite (preferably in sub-domain configuration instead of subdirectory)
Could I make some of them RTL and others LTR
Yes, obviously … That should happen based on the locale set up for the particular forum
