Subject: Re: [Star-tpc-l] TPC Meeting Minutes
Hi Frank,
Thanks for your rapid response to this issue in the minutes! Yuri
would have to provide the details of his pending request(s), but I am
happy to serve as an additional approver. Please let me know what's
required to get that done.
Cheers,
Richard
