some points keep coming to my mind-
1. i think a person should be allowed to delete his account on jatland. (although we can still follow the existing rule - ki ruthaniye bateu manaae nahin jaaenge - jaate ho to jaao)
2. a person should not be allowed to erase/delete/edit what he has submitted. he can do a corrigendum in next reply if needed. moderaters can censor vulagar language if submitted.
