Hello archadmiral! Just by posting on this site, you have already become a member. In fact, we have lots of member who either live in the Philippines or are Filipino! There's actually a
thread on the Countries sub-board for the Filipino members (btw, I'm from the Philippines too, although I don't live there anymore).
There is no login and no accounts, but if you want to keep your name unique, you can go to the help section and use a tripcode. You can test your tripcode in the Test sub-board under Random (to see the sub-boards, you have to click on the main board it's under).
There's a chat where you can meet people and make friends, although you could do that too on the different boards and threads. If you read the Description + FAQ thread on the Main Board, it'll help you understand the organization of the site and avoid preventable mistakes. I hope you enjoy your time here, archadmiral! And welcome to the Dollars!! :D
