Someone can point me in the right directions
Hi @andyb_Best , and welcome on the OpenPlanetary Forum.
Please understand that it is not easy to answer questions without too much of context… 
Anyway, if I understand correctly from your question on Slack, you need information about the GMAP Winter school?
From their information for participants page the right place for follow-up is their Discord server. You should have received an invitation by e-mail if you participated to the school.
