Unable to post in "Official tutorials"

Likely newbie problem, but here goes.

Iā€™m unable to add new topics to the group ā€œOfficial Tutorialsā€. The button in top right corner is greyed out / disabled.

Does this mean that the group has been closed for new posts or am I doing something wrong?

Same thing for me, just read a bunch to posts, and youā€™ll be good to go.

@modnar @javelin Do you still have issues with this?
