Are badges automatically granted or do I have to trigger it?

So I've had about 12 hours to dig my way into the code for the Mod and figure out my way around the stock badges etc.

Are the post badges given automatically or do I have to trigger the event to "re-badge" users? What I mean by this is that if someone registers and posts one time will they receive the "1 Post" badge automatically or do I have to trigger it myself and then everyone who has made 1 post will receive their badge? Essentially I'm going to copy the 1 Post code three times (with small edits here and there to make it work) so that when a user registers, and posts a single time, they will receive three badges to their account. I figured this was the only way to get around the lack of "Registration" badge(s).

You should rebadge all members otherwise the badging only occurs when an action such as a post happens/changing something.

Ok, so in other words if they have 99 posts and they make another one, bringing them to 100 posts, they will AUTOMATICALLY get the 100 post badge. This means that I don't have to trigger an event to give them the badge as it is done automatically. Nice.

Hmmmm now that means I need to go into the mod and code it so that upon their first post they are automatically awarded 3 different badges.

Tricky tricky.
