I usually use my phone or tablet to respond to the forum, but I really don't like to. If I'm quite frank, I think the mobile version is terrible. It isn't necessarily what it does, it's more just how it's presented. I can't tell whether there are any unread posts anywhere, just because the size of the icon is too small. Also, when I come out of a sub-forum, it still says I have unread posts there. It really bugs me. I would like it so that it is more customizable and convenient and easy to use. If it was me, I'd make the mobile version less grey and improve some of the icons. Sorry if this came across a little bluntly.
