I had been facing this problem from quite some time. Suppose I want to practice the D problems of all recent contests or any particular problem of some contest. So whenever I would open the problem, the tags would be visible to me which I don't want because I want to think about the problem from scratch. The only solution I saw was to make it a virtual contest and then do the problem. But this also has downsides because maybe I would like to read the problem now and then open it again tomorrow for some clarification. Then I would have to start a virtual contest each time I want to view the problem.

Now I use the "Complete problemset" link located below the problems on the right side (wonder why I didn't notice this earlier) which enables me to view all problems without constantly trying to not look at the tags. I hope this helps people facing a similar problem.

Edit: Schullz has given an even better solution: Go to your profile -> "Change settings" -> "Show tags for unsolved problems"

Daylight saving time has ended for this year. There will be a 1 hour time change for many countries. So pay extra attention to the contest timings in your local timezone. Happy coding!

PS : For Indian participants, the regular CF rounds will start from 10 pm instead of 9 pm. Yay!

Edit : Here I am telling everyone to be careful about contest timings while comfortably forgetting myself. I saw the time for today's SRM (638) a week before and never bothered to check again. Result, I woke up at 6:15 am thinking that the SRM would start at 6:30 am while actually it was to start at 7:30 am. Damn you daylight saving!!

I would like to request the Codeforces' admins to postpone round 217. The timing for this round clashes with the Facebook Hacker Cup. The Hacker Cup will take place from December 7, 2013 at 10:00 AM PT. http://www.timeanddate.com/worldclock/fixedtime.html?msg=Facebook+Hacker+Cup+2014+Round+1&iso=20131207T10&p1=1240

Even though the Hacker Cup will last 24 hours, many people might not take part in this round because of that.
