One can login with facebook or google if the forum is setup to allow that
Still there - viewtopic.php?f=436&t=2438221
The style in use here, prosilver SE uses fixed width at the moment, which we are planning to change, but is already responsive the other direction (smaller screen). The standard prosilver is already responsive for large and small screens.
It’s been discussed to death elsewhere, please don’t start another discussion on the subject. It would be much better if you went over to phpBB ideas and posted your suggestion then you’ll see.
The answer was pretty clear I thought: post the idea again since it's an old "idea" (not even sure why it's locked to begin with). However if the point is to just criticize and berate the volunteers and developers here, as you have already done a few posts above, then please don't bother posting the idea. Thanks.
I can see it OK on the Index page
Even if it was a link to Ideas is always available under the Development menu.
