I renewed once for credibility purposes, but it’s probably not worth it. I don’t think companies are really checking for it and I don’t think it has the credibility that I thought it did. I did call for advice a few times when I first started, but now I don’t need their help. Never gotten a contact from signingagent.com, either. Sooo… idk. I was also apart of my local Chamber of Commerce for a year and didn’t renew that one since it didn’t lead to any connections like I thought. And I don’t think people really cared about the membership lol. People don’t ask for it when offering jobs/making appointments.
So, it’s up to you. I guess it may boost credibility if it’s posted on your website.
