@Andrea6232 was right, it's just your Community Center participation level that's Level 1. It has nothing to do with hosting, it just shows you haven't interacted much here so far.
Yes @Warren276 it won't count against you as a host or against your listing at all if you're not acrive here, so in that sense the participation level is not important. But as a host it's a very valuable place to learn from others, and you also get a chance to assist.
