I only recently filled out the “about me” portion of my RM profile. I was pleasantly surprised when one provider I was communicating with commented on how helpful that information was. As with all things YMMV but this guy checked me out after I contacted him and, yeah, that makes me more likely to book with him. With this hobby, communication is key, but there are few absolutes about how, when, and where. I figure if putting information on my profile helps, why not?
