Nice to have you on this forum. It was a bit surprising to find the website format change so drastically but it looks ok to be honest.
Good luck with your new responsibilities.
A few things:
1) Posting a reply. The smilies on the right hand side are so bulky that they use loads of space. As such, there is a big empty space beneath the opened "post a reply" field that prevents me from seeing the post of the person I want to reply too....lol...if you know what I'm saying.
2) A guide showing the changes could be useful maybe?
