I have not power on the site but I think I can solve your little problem in a way!
Looking into your problem I found the problem right off the bat- you are not the author of the initial account. Not sure if a moderator can help but the easiest way around that is to start your own author page and give a link to the previous page to say time and effort transferring all that is up! Doing that will give you the full power to modify the page at any time while your account is active!
If you would like I can go through every posting you have made, extract the story locations and send you a master list that you can then copy and paste in a topic you start! I'll do one like I use for my three accounts here on the "Author And There Stories" topic without the sub topics heading!
