Rather, I planned to remove accounts I no longer use.
It is not the "to save some space on the web" reason (that is plain redundant).
I just no longer want to have so many web accounts in my brain XD.
No wonder, I couldn't find it. I originally thought members could do it.
The reason I planned to remove this account is because I have been inactive for a year or so.
I was just about to ask the same question on Comodo Forums
