This may not be a big deal but I find that most pages on the giffgaff website follow a clean graphical look apart from the community page. I have done a mock up of a possible solution.
Anyone who feels strongly about this could look into finding someone who can design that page with shortcut links to the relevant giffgaff boards and then host it somewhere.
Although there is a point that smartphone users might like the buttons or icons look, it's also true that images use a lot more data than text, and the mobile version of the giffgaff forum is more minimalist than the main.
Sounds really really cool but I guess the ppint mae by giffgaff makes sense. Though i have to say, I don't think newbies would be confused for long by it, they'd soon get used to it surely?
Personally, I prefer this design to the current community page. I don't think it looks confusing at all...
