In the i3 sub forum, the general discussion is labeled as i3 and i4. The i4 is a non existent concept from at least a couple of years ago that really dates the forum status badly.
It would be good to keep the sub forum naming consistent with the current lineup and remove the i4 reference. It's been mentioned multiple times within the i3 forum, so want to report it to the dev team for the wider site/app and try to get it updated.
