Hi kudataz, thanks for the question!
We're on WordPress 4.1 with this code and it's still working.
Related, see http://fwdlabs.com/resources/code/wordp … nbb-forum/ for more up-to-date code releases.
Regarding your questions on the config:
* $punbbUsername should be a real username unless it's intentionally to appear as a bot aka non-user (which isn't the intention here)
* $punbbUserID should match the real username or may create a problem, since it wasn't built to run as a bot / non-user
* $punbbUserIP can be spoofed and is a required variable that punBB wants to store, generally for security purposes
* $punbbForumID should be the forum ID known within punBB so this auto-post shows up in the right spot
Let me know if you have any other questions or concerns. Thanks again!
