We could upgrade/tweak SMF to be more mobile-friendly, I believe. That'd be my preference, probably.
Is there nothing out there that would be mobile-ready from the start?
I have had a look around and SMF seems to be one of the most feature rich of the free forum software platforms. That said looking into the 'better for mobile' software I have found Discourse (www.discourse.org
). This is an open source product (although the main site does appear to encourage you to take up there hosted option). It does have a feature to migrate from SMF. I had a look at the Altassian developer community forum, and the Mozilla forum, wikipedia says they are both discourse sites, but neither mentions that is the underlying software. They have very different layouts, suggesting there is a lot of flexibility in setup.
The other software I looked into that seemed good was MyBB, I have not looked at any of the sites based on this software on a mobile device.
