I'm your R2 OST opponent. I'm GMT-8.
My availability (for both this week and next week) is as follows):
Mon-Fri: after 6 PM
Sat-Sun: whenever's good for you (within reason)
Let me know if there's a time that works for you. I'll just toss one out for you to consider: 12 PM (my time) on Sunday, February 18?
