Yes, this is normal.
There are restrictions in place for new accounts, as explained above. It has greatly reduced the problem of spammers on the site. Read around and post for a while, and the restriction will go away. 99% of the time there is an existing thread that would be appropriate for you to post in instead of creating a new thread.$bbuserinfo[username], you do not have permission to access this page. You've either gone to something that no longer exists, or you're a brand new member and trying to create a thread, which we don't allow. If this is the case, please feel free to contribute to existing threads, and soon you'll be able to create your own. This cuts down on hit-and-run spammers, and you'll also probably find that a thread you want to create already exists (try using the search function, it's great!).
