@iChars : We actually took a wrong approach on GroundHogg, instead of API's we will now add core functions as GRoundHogg uses same WordPress setup.
The mentioned features, adding to this topic are still in todo list.
1. Assigning specific tags to a contact in groundhogg when they complete a course in wplms
2. Assign courses in wplms based on tags added in groundhogg
So, this is going to take some time as we want to press on to WPLMS 4.0 target of 10 March.
