Andrey Chadin request

Andrey, Hi! Much glad to see you again - hopefully you are fine :)

As to your request, I'm sorry if this sounds discouraging but as explained at the certification page somewhere:

we do not "upgrade" certificates of Bishop and Stargazer (say, to Zealot) - they are of equal value and it makes no sense to hold more than one :)

I'm thinking instead of introducing some different type of achievement, not related to amount of tasks (like medal for getting into Top-100 or something alike) - so hopefully just wait a bit, it will come one day :)

if will be new certificate for 150+

You see, it is one of the issues with "certificates" for problems - if there are too many of them, they quickly lose the sense... :) You know anyway, real value is not in papers, but in you yourself, skills and wisdom you gained :)

UPD I decided to give up at last and provide these "duplicating versions" of certificates for those who really want them much :)

Yours is added to your profile! Thanks for being with us that long. Hope you are fine! :)
