As has been mentioned many times already...

Everyone's previous points have been saved.

Once we're ready, they'll be trransferred to the new system.
They will all be lowered equally.

As for posting. Some forums are different from others.
But as a general rule, you get 0.5 for a new thread and 0.1 for a new post.
You get 0.001 everytime your thread is viewed (by members and guests - seems low, but this will add up faster than you think).

The Profile credit, means that you've filled out all the fields in your member profile.

There will be an integration with the arcade like it was before. Each game will cost something, and high scores will win you a jackpot.
