All is in the topic's title.... But i have to mention here i've registered a month ago. Way passed the 24 hours requirements & i've found no other restrictions unless i didn't looked harder.
Your profile reveals ZERO games credited to the account's register, so there are MANY forums you cannot post in, because those require an updated profile, such as my own. Observe the Icons under my forum Avatar image. I can post in the restricted forums for only those three games, but I certainly *can* post in the ones that I have registered fully.
