Hi Jiaju

I am testing about working of booth while investigating booth source code.

I don't understand ticket grant and revoke process perfectly that is 
related to connecting each booth
so I would like to know booth's working that would be matching your 
offering source code.

Could you give me information about booth sequences that would be the 
ticket's grant,revoke,lease logic and working of ticket's expiry time.

when do you think the booth's working is fixed and completed ?

Is there anything to help you about booth's implementation or etc?

Best Regards, Taihun
