This is still a work in progress but I would like to know if I’m on the right track Speaks say Boo
From a Mobile point of view. The forum looks a bit washed out, lots of the stuff you've styled isn't seen.
Using a phone in Desktop mode. The whole forum isn't wide enough, I'm guessing it's set at 75%, up that to 90% and test, see - www.proboards.com/admin-guide/themes-styles/changing-forum-width. Also the height of the title image is a bit big, it's pretty but only means people have to scroll more on a small screens on every page. And remove the "home" link from the title text that's an accidental tap waiting to happen and can be a bit annoying. Better still have the text as part of the image. A minor one but for some reason the thread & post count columns go a bit off each category, it sort of zigzags.
On both views the Back/Top graphics at the bottom of the page are very blurry.
Apart from the Gaming Board description being far to long, I like the structure, it has lots of room to build upon. Looks clean and considered for what you need.
