Most likely because you're currently on "newbie" status like me!
You can increase your member level here by posting. But remember, the DeepOnion team want to see quality posts... and hopefully you do too!
Don't rush into it, read and learn (if you're new to the scene in general).
It takes a few weeks to go up member levels (because the forum works on 'activity periods' which update every 2 weeks - and you can only gain 28 points in that 2 week period)
Good luck!
