Yestersday, WizKids Games announced a rejuvenated Event and Replacement system, effectively called WizKids Event System (WES) and WizKids Replacement System (WRS). It looks like these portals contain the current state functionality and are simply an aesthetic make-over to users at this time but new features will be coming soon.
For now, the new WES and WRS aim to replicate the same functionality of the old systems in a more intuitive and efficient manner. The goal is to make these systems easier to use and speed up your interaction with the system. The WES, in particular, will include some great new refinements and makes it easier to find events and stores, and for store owners and volunteers to report their events.
