I keep getting a 0% warning level. What does it mean?

The warning level is our way of formally keeping track of rule-breaking. If you constantly break a rule or break a major rule, you will receive a warning, which expires after a set amount of time, and is also worth a certain number of points (1 point = 10% warning level).

By having a 0% warning level, it means you either have never been warned, or you have no "active" warnings. In your case, you have never been warned.

The warning system is used then to issue automatic punishments: 50% means you will be placed on post moderation for a week, 80% means you will loose your posting privileges for a week, and 100% means you will be banned from the forum for a week.

As long as you follow the forum rules, you should never have to worry about warnings.
