mixingbowl

how to get into it
do they have invite system or i just have to wait for registration to open?

No invites at the mixingbowl and I don't think it will open up anytime soon. Ever since they had some legal trouble it's a closed tracker only for members in good standing before the attempt to shut it down. Maybe someone will give you an account but I find that hard to imagine sorry m8 and good luck it's one of my fave trackers.
