No future categorie in the menu???
Since when was there a “future” category?
What do you mean by “future category”?
Is it the features category you are talking about?
The Features category is right here
Are you TL1? If you are, that restricts you from posting in features and thus it won’t appear until you become TL2.
Also, the category you were trying to post was a duplicate. Please see Boeing 787 Family instead.
