Your account is activated already, you have to have 5 posts to see your posts / threads right away, before you have those they need to be approved by a mod.
Can you email webmaster@freeones.com with the problem and also give some more information?
Like what browser are you using, is it updated to the latest version.
Are you on a PC, Mac, mobile device
I checked your account and could see the "post new thread" button just fine.
I also noticed you actually created a new thread about half an hour after your quoted post so I assume you finally found the button?
If you still have problems please email webmaster@freeones.com and give us more details such as what browser you are using, what device and so on.
