Anyone can apply the Request/Bug label to their own thread when posting in this board.
If you find bugs or want to provide feedback to the current theme you're using, please create a thread and submit your post like this:
THEME, Explanation, Screenshot, @regack
Please provide a screenshot when possible, as it is difficult to work off of written description; a visual will be easier for us to tackle the issue.
As far as mobile issues go, there are limitations in that ProBoards does not provide a template for modifiying the mobile version of the site.
