For the last few days there was no edit option for leading paragraphs for me. When I browsed my preferences page, I found on my user profile, Member of group was  mutilated as well as on gadjets tab, there were nothing against Appearance. Hence my option of add edit link to the leading paragraphs was not working. I dont know why my Preferences page got mutilated and I seek your help in setting things right. From the discussions on this page I undrstand this problem exists for other users also.
