I think you can.
Some other forum members changed their usernames. Unfortunately, I am unable to access the website. It says, "Sorry, you have been blocked," and the title says, "Attention required! "| Cloudflare. "So, I assume Cloudflare is blocking me from accessing the website. I have also tried VPN, but it didn't work for me. I think The Cryptovator can help since he also changed his username, or he probably changed his username while he was signing up. I don't remember the sign-up process at this moment.

As for the image issues, Bitz team members love to use ibb for some reason (LOL). I have been talking to the team members for a while to take a look at these issues. They fix the images and then it happens again the next day.
