We completed all the milestones (except integration with OSO which will happen in next couple weeks). Feems from Plurality Labs has been helping us run workshops every week to onboard Arbitrum grantees to GAP. We have run 3 workshops to date and the turnout has been good (ranging from 20 - 40 users) per session.
Contributors have also started reviewing various grants. You can see example here.
