I have another doubt. If I use joomla inbuilt login then its works fine. But If I use k2 user login its says "SSL connection error(Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.)". How can I debug this error???

Also I want to configure If the registered user post any post/comment then its directly publish to the frontend, when that post/comment don't contains any unwanted words. otherwise only it will goes to admin approval(If any unwanted words in post/comment). How can I do this functionality ???
