Suggestion:

Add a redeemable incentive for linking your game account with the Discord server.

It doesn’t have to be anything with monetary value or game breaking, a simple token that could be turned in for 2 hours of double experience for example would suffice.

This holiday event has been a great way to capitalize on growing our playerbase, our administration needs to take it a step further and own in on the potential.

There is lots of ways this server can be fine-tuned to improve the overall player (customer) experience.
