I had access to that part of the forum before, I could read and write, but now I can't see any threads there because I "do not have the required permission"....

Erm, have you deleted some of your posts? Because you need at least 9 posts to see all the threads from this forum

Nope, I did not. But something happened and now I see all of them...

Hey Merse;

Before you do post count of 8 you won't be able see several forums. This means that you are in the group called New registered users and 8 posts will auto-promote you. During the time you are in NRU group your access will be limited such as; Unable to message users, post links (imgur, prntscrn as exception), Read and post on several forums and other. Soon as you get 8 posts you will be given normal access to things. However, as NRU you are able to ask for assistance or report issues. As a NRU you are also given the chance to socialize with rest of the community and let us know more about you. This is one of the system I put in place in order to boost the quality of socialization and prevent unnecessary spam.

I had this problem too, glad to know how to fix it xD

Not that hard to post :P Only 7 doe.
