Meetings
The 20:00 to 21:00 slot sounds fine. I’m notoriously bad at making morning meetings.
Synchronous
Chat is fine. But my ZNC bouncer is currently down. I haven’t bothered trying to get it set up again because I keep hearing that there is a (fedora account sso authenticated) Matrix server that will be up and running very soon. 
Asynchronous
I guess a Discussion category sounds a bit more reliable than email. Emails have been known to get lost from time to time (especially in my inbox).
Tools and process
I have virtually no experience with Pagure and only a little with Taiga. I’m not really knowledgeable enough about the systems to make a call.
See my response to the previous question.
Assigning tasks sounds fine to me. Do not worry about making me “feel bad” because you have not assigned enough work for me. On the contrary, my skills and familiarity with this whole system are so low that I would very much appreciate a very soft/light start.
¯\_(ツ)_/¯
Edited to fix shruggy … don’t want to upset the FPL … I’ve seen his murder attic.
