Please keep in mind that all team members must register AND validate their CPID in order for them to participate in the Marathon and Sprints. Pututu from [H]ard|OCP made a nice tutorial on how to validate your CPID.
If you have any problems please feel free to respond here or reach out to me any means you are able.
Do not send me PMs. The PM system here doesn't notify like it's supposed. Contact me through Discord (link at top) or post in the forums here. I check those regularly. At least until I figure out the PM notification problem.
