In my wiki not appears the option "Forum" on Wiki Features (Labs). What is going on?
I would like to use this new feature, someone could help me?
The Forums feature may not yet be available in your language. It was initially released for English language wikis only, and I do not know if this has been expanded to other languages yet.
Checking my wikis, it's available for some foreign languages (Polish, German, Spanish) and not others (e.g. Dutch, apparently Brazilian Portuguese)
My wiki is in Brazilian Portuguese. =/
Unlike the other languages, I don't have a Brazilian Portuguese wiki to test it with. I said that it "apparently" didn't work in the language because of your situation.
What do you think?
