This is normal and is going to be the case for everyone. I would recommend for the future that when using these forums that you make sure to use the search feature to find if your question has been posted already.

However to let you know, you need to be level 25 on your character ingame to be able to create a thread. There are restrictions on these forums, which aren't like others you will find on other gaming related forums. So always double check before posting as you will be limited per day.

It's a way to avoid spam and to make the moderation of the forums easier for the community team. So overall it's an inconvenience for some, but it will result in a far cleaner forum to read through.
