There is a feature of HackerEarth to auto-register for some contests which are held regularly. I was curious if it can/should be added to CodeForces too. If this is already here then Please tell the procedure to turn on the same. Discussions are welcomed.

Do tell if this is available on HackerRank, CodeChef or AtCoder.
Thanks.

Are there any working tools for these? If yes then please paste links.

Thanks. :)

I tried to check my rank among my friends based on rating but the rating hasn't been updated for about 2-3 contests. What might be the problem? I am using this user : jonsnow7 for reference. This is the link.
