Hello. From my experience so far, people usually tend to use Feedback forum when something is wrong, or they have a complaint, which I find unfair. I just wish to let you all know that you have a wonderful community here, and I quite enjoy my time on your website! You probably don't know me, since I spend most of the time on this forum reading. Hopefully, some day my maths and physics skills will be at a level where I could actively contribute without embarrassing myself. Now, from top of my head I am unable to come up with any "areas of improvement". The only (minor) thing I can come up with is the fact that your PF app does not support Latex codes, but I'm sure you're already aware of it. I use the app quite a bit (I find it to be "healthy" replacement for Facebook; if I am to procrastinate, at least PF makes me feel less guilty about it). Anyway... Keep up the good work and all the best!
