I thought I have a message or something - I went to check my inbox and re-read my only (old) message. The dot disappeared for a while. Now is back again. No new messages.
Hi… The dot is an indicator of your online status !!
You can see it also at right side of nickname when messaging with others
This is also helpful for people looking at your profile to see if you are online in case they want to send you a message and are hoping to get a quick response.
its a indicator of you are online now in fiverr.
