Hmmm. I always browse and post here from my phone. Have never had problems using the regular version on the site.
I could always view and post. But posting using the forum editor was troublesome on my phone using the normal version. Viewing the forum was fine but the normal version isn't mobile friendly at all. Most forums aren't in the normal skin version. Usually there's a mobile skin, an app, or a stripped down version that can be used. I did't see one on this forum until it was pointed out.
I'm also used to Repeat Offenders forum so I got used to having a mobile skin or Tapatalk. The stripped version for this forum works just fine with my phone.
