Forum Bots

I was wondering if anyone knew of a tutorial of how to make a forum bot for a php forum. The bot doesn't need to be smart and answer peoples threads/posts but it would need to be-able to make posts.

This would be used for private use only on my own forum.

Thanks In Advance

The basic concept is to insert a line of code at an appropriate place, calling a custom function that does a SQL query, such as an INSERT into the posts table.

For example, to make a Welcome bot, you would execute an extra SQL after a user successfully registers, inserting a post into your Welcomes forum.

How exactly you do it depends on the forum software.
