Hey Bitcointalk fam! 
So, I've been aware of this community for like 4 years now, just kind of hanging around the edges. But I've finally decided to jump right in and be a part of the action! As a newbie, I'm super excited to soak up all the knowledge you guys have been sharing and maybe even throw in a few of my own ideas about Bitcoin. Let's learn and grow together.
Welcome officially to the forum. Four years and you still managed to resist the urge to create an account on the forum. Well you should be familiar with the forum by now, its not much different from what you experienced as a guest, I believe the only restriction you have as a forum guest is not being able to post or send messages. I hope you can use forum search engine, this thread will help with that. So, I've been aware of this community for like 4 years now, just kind of hanging around the edges.

That would be Bitcoin board. Before anything else, I think you should refresh your memory of the forum rules.
