[coc-tf] Poll for Regular Call

Dear TF members,

Here's a poll to find a timeslot for a regular call (Starting 2 Nov and 
recurring every two weeks).

Salam has said Mondays are generally better for her, so that might be 
one to aim for if possible.

Note: this time around the timezone is UTC(+0) rather than Amsterdam 
time/CEST:
