Automatic Posting in Specific Forum Thread

What I am looking for is rather very simple. I think it should not take more than few hours to write a code for it. All I want is a little tool or a script that would automatically keep posting messages from a list of messages to a specific THREAD in a forum.. I want it in a way so I can setup the time delay between each post. Here is an example- There is a website www. website . com They have forum www.forums. website . com There is a specific thread in this forum www.forums. website .com/XXXX User YYY wants to post a different message in this specific thread each 10 minutes. User YYY have a list of messages that he want to post each time he clicks REPLY. The list of messages in a .txt file (it can be any format all i want is that it has to post from a list of messages) The code copies the message, pastes it in the thread clicks submit and then waits according to the delay and then posts again when time comes. There is no CAPTCHA deal. There is no user creation Everything is ready all the tool has to do is keep posting the message in that thread. Any questions please ask me..
