Yes, it allows me to build the workflow on the discussion board and update the workflow settings. However, it does not acknowledge the workflow when a discussion "item" is created or modified on the list.
Ok I got this to get in the workflow when I took the conditions off the workflow. I put a log history. That logged. Then I added a Run If and put a log history in that and it ran.
Join the club. I've been teaching myself as well and am also a site collection admin. Thank God I don't have to do Powershell stuff.
The Log History action is great for troubleshooting. I use it a lot to see how far I am getting in the workflow. It logs entries in the workflow history. So you can put variable values and all kind of stuff to see if you are getting what you expect. I just don't recommend leaving those in there when you are finished troubleshooting. They take up space in the Nintex database.
I did try that and it would just put my name in. I read on that and it says "username of the user who started the workflow, or caused the event which trigger the workflow."
So if I reply, it will only use my name to reply with. It needs to pull from the previous post username. Using the ParentItem property like you did makes sense if I could find it.
