Meet: problemset
By MikeMirzayanov, 14 years ago, translation, In English
Codeforces had accumulated a many interesting problems, so it time to make own problemset. So today was not in vain – I’m presenting you the problemset of Codeforces. Perhaps the only reason we need it - is to make it easier to solve problems after the contest and understand what solved, and what does not. There were request in comments. I do not think that it is important feature, but someone will be more convenient: and it was good.

    The same to me.
    The "Who" at problemset status is always wrong.

    This bug happens only when I submitting files.
    If I submit code via textbox, everything will be ok.

Sometimes I submited, but I could not see my submission in MY SUBMISSIONS or STATUS.

id #240733 - #240763

I found this bug as well when I submit both in practice and problemset.
I submitted 36E many times, and each time I submitted it, it shows a different handle did so.

Nice! I think tags for each problem (for example, 'binary search' or 'dp' or 'graphs' etc) will be useful too!

    But you should be able to hide them. For some problem the major difficulty is to realize what kind of problem it is.

some early images seem to be broken. such as
10B: http://codeforces.net/renderer/de21a9bdfc2f66814cc5291ec42a9813f7f3b391.png, http://codeforces.net/renderer/a6ae5b08ea1c4d15f150b1a9df3c925c2b9cdd51.png
15E: http://codeforces.net/renderer/5945210be972aa5fe947f3b8a3a0378a4cade844.png
it's hardly possible to understand the statement without these images

i also recommend that the alt property containing the latex format formula to be added to the image tag. in this case, formulas are still easy to understand even when the images are not available.
