Are registration fees for a forum for external speakers (not partners and not associated partners) eligible?

For external participants (neither associated partners, partners, nor speakers), registration fees are not eligible. We recommend covering these costs directly, considering the already significant support provided for travel expenses.
For project partners (PPs):
-Travel and accommodation: CC3
-Registration fees: CC4 (External Expertise & Services)
For identified speakers and associated partners:
Travel, accommodation, and registration fees: CC4
For target audience:
Based on the interpretation aligned with Article 42(o), only travel and accommodation costs should be considered eligible. We advise against extending this interpretation further to include additional costs such as registration fees.
