It's really good that we have a tag called predestination which would take into account the Calvinism doctrine, and furthermore, the term predestination is more descriptive and indicative of what the doctrine is actually about which is Predestination, and therefore, we do Not want the tag Calvinism there.
However, could you please also add tags for the following five points of Calvinism(TULIP):
Total Depravity(total inability)
Limited Atonement ("particular redemption" or "definite atonement")
Irresistible Grace ( "efficacious grace" )
Perseverance of the Saints ("perseverance of God with the saints" and "preservation of the believing")
I still need to read up more on the terminology associated with Arminianism doctrine, but could you please also add tags for terminology associated with Arminianism doctrine?
