Please allow us to delete threads or at least edit the post... I want to remove/edit some pictures because they show the UID, which I've been told is dangerous as people can use it to enter the account.
Members are not allowed to delete their own threads for security reasons. However, editing the contents on the 1st post of their threads are allowed though for just a brief period of time in case something like what your concern here happens. You can follow @Middleman's instructions to ask @Admin to assist you here.
