@bosd why did you close this one?

[bosd]

@JordiBForgeFlow I closed this one, as it seems this module is no longer needed.
This module only adds the forwarding button to the view.
The forwarding button is now included in base_tier_validation_forward.

edit:

          There's no need to port `account_move_tier_validation_forward` since the full functionality is already provided by `base_tier_validation_forward`
