Is it really necessary to sign up for Codidact META when already signed up to Codidact?
I was expecting to be able to switch to Codidact Meta (https://meta.codidact.com/) with a single click on a button somewhere on Codidact (https://forum.codidact.org/). I have not (yet?) found such a facility and I'm afraid anything more (even one time) seems to me pointless trouble. But it would bother me less if I was aware of a good reason.
Possibly related: Once into Codidact META I don't understand why "Ask Question" informs me "You're asking a new question on the main site … ".
