I would like to implement a forum bot, It's dutty's would be starting a new thread and reporting the right url back to the module that requested the new thread.

Now I was wondering, should I try and use the new event system in 4.3 to try and implement this asynchronous? Or should i just write a controller class that does this job syncronously?

Is it possible to set up a forum where all my user can reply to the threads started by the bot, but not start new threads themselves?

Wich forum controller classes should I lok at to accomplish this? are there any gotcha's I should be aware of before starting this project?

All who will answer, thanks for brainstorming with me :)
