I don't know what the webmaster(s) here are trying to achieve by making the icons larger - as they are now for a month or so - and the fonts smaller - as a consequence of that new sidebar (!). But the forum is becoming more and more unreadable on smaller and even bigger devices - and I replaced my glasses not that long ago.
May I suggest either reading some books about web design or some articles about presbyopia... or both?
Or maybe that's just me and the web has changed again while I was sleeping - to meet new social networks and other fancy requirements.
