There was a forum on which I wanted my account deleted, and, like here, there was no option to really do that myself. I asked, and was told that, like here, I had to ask the higher ups.
I wanted my account deleted because I was really, really tired with some people there (there were many occasions to meet them IRL) and I did not want to continue going.
I was given two options: all of my posts stay, but with the "Guest" name, OR deletion of everything. To avoid confusion because I was told my participation in certain threads was "interesting" , I accepted the "Guest" option.
I do, however, understand that someone who, for some reason, might be really, really ticked off, complete account deletion would be important.
For this reason, maybe there should be an option to archive someone's posts where regular posters cannot see, and then wipe the account and board so that people cannot find out. Or something. And then this should all be outlined so that we know what is done about it ?
Oops, sorry for the rambling.
