[Python-Dev] Git hub : CLA Not Signed label

[Anthony Flury]

All,
I submitted two Pull Requests last Sunday, only a few hours after I 
signed the CLA.

I understand why the 'Knights who say ni' marked the Pull request as 
'CLA Not Signed' Label at the time I submitted the Pull requests, but I 
was wondering when the Labels get reset.

How often (if at all) does the bot look at old pull requests ?

Thanks for any help you can give, I am sorry if the question sounds basic.
