The best thing to do is to acquaint yourself with the people to the extent you can. The Forums are a reasonable place to start, but should be supplemented by visits to the CoE Discord as soon as you feel comfortable. I say continued visits because the cast of characters changes, and you want to get a good breadth of samples. After that, you should familiarize yourself with the various kingdoms on the various servers, and pick one or several to concentrate on, based on server convenience (lag, basically) and personal fit.
As a Proprietor, you will be more directly involved in community relations and politics than a basic Adventurer will likely be, just because you will be owning land and/or setting up a business. Each of these makes picking up and moving to someplace more suitable more difficult, because you may very well be giving up a bit of real money and/or real time investment, the former in the form of any static property you have spent EP on, the latter in the form of any goodwill and personal relationships you have established in your original location.
