Just a dumb observation/question but what makes it difficult to see the different sub-forums? The first few times I noticed some having trouble with it I assumed "less than average intelligence" or laziness, probably because the layout is so obvious to me. It seems to keep coming up, is the main forum page a totally different "look" on certain devices? I'm on my tablet or PC mostly and it looks the same whether in mobile or desktop mode.
Am I just old and used to standard forum layouts? Another instance of FB having a negative impact on communication or reading?
