Ok, now I understand. Your account is new, so some of the functions are still locked. This security system has been put in place to dissuade spammers from participating at the forum. You need to have a certain amount of posts before you can be authorize (or activated) to open threads or to post links (pictures, videos, etc.).
This is what you need to do, you can post your question on the "ask questions" section for a Mod to see, or you can send a private message to a mod asking for activation. Mods are everywhere but they tend to gather at the "introductions please!" section to welcome new members (I also recommend you to introduce yourself to the community). Good luck!
