I am using joomla 1.7 and jomsocial 2.2.4

It seems to have a lot of bugs in that a normal registered user on jomsocial can behave as an admin;

1. as a logged in user i can 'unpublish' or 'delete' a question even if it is not mine??
2. as a logged in user i can 'accept answer' even if question is not mine??
3. as a logged in user i can 'change to open' an answer even if questions is not mine?
4. as a logged in user i can unpublish and appear to edit or delete an answer even if it is not mine??

Surely only the owner of the question or answer should have such powers?
