JF new logo and more…

I’m glad to present a new logo for JF! No, no, not my work, a professional one. 🙂

And together with a new logo, a new look of Original Problems page, the one you can see if clicking on the  upper menu. It’s not only about the list of informal competitions presented in the table now, but also about the links to the Awards added for each competition for your convenience (I hope!).
