If you ever go onto the invisionfree support board,you have probly seen me there . I volunteer alot. I havent found a code for an invisionfree bot yet either. Some coders said they would try doing it, but they kind have dissappeared . If I find a way to do it, I'll let you know as soon as I know something
Have Just setup a forum bot with the Program E AIML platform on a phpBB forum. It is self described as being an advanced mod. So don't let initial failure discourage you.
Basically, first setup the database, then install the PHP, then load the AIML files via a PHP script. Trick: load the AIML files a few out of a time. For example: Copy 1/3 of the AIML into the directory then run the script to load them to the bot brain in the databaswe, then delete those AIML file copies, then repeat the process for the all the rest.
You only need all the AIML files in the directory to wipe the brain clean. Otherwise it is okay to delete the AIML file copies after loading them.
With some patience, it will work. And it is alot of fun too!
