Is there a limit on offclassing?

I don't use discord H2OGamez. Also thank you for answering my question

Pls help.

is too short (minimum is 10 characters)

my week 3 match showed up earlier this week and now their team captain thinks today is week 3

are the normal matches just scrims?

Chaos

My team (MWR) got a match against Skibidi, however when I checked the notification there wasn't a page for the match

If I need to have a ringer instead of one of my full time teammates, will they have to be signed up on the website?

another question I have is does the ringer have to be in the same division as me?

nevermind, figured the thing out

I'm not gonna tell the whole story but one of the members of my tf2 team is not responding to me, has blocked me on steam, and I think has left the team without telling me, and I need to know if I am able to make a last minute replacement.
