Theoretically yes, but meanwhile HiFo board decided to terminate itself and hand over all assets to MC eV. MC e.V. and HiFo co-existing was a possible model where the eV would be a "Förderverein" only. We thought it eventually would be doable for a regular bank to have signers accepted EU-wide for an account with reasonable fees + charges, but that's yet to be seen. Chemist is after it. Yes, those 3 boardies signing at court have to be EU citizens or residents. But since board positions so far are unlimited, everybody may participate in addition.
Quite the ego you have there. A non-native speaker, telling a native speaker he doesn't understand the language.
admin channel access is controlled via invite-exempt list (/mode -I), in the very beginning it been based on access-list (/msg chanserv help access). You been on both lists from the time you first got invited into admin channel and showed up there. When you don't authenticate to nickserv, you can't get identified by neither of both lists and access cannot get granted. When your client tries to autojoin protected channels on client startup, before you authenticated, then you'll run into trouble. Nothing a chanop could do about that, call that "refuse to fix" if you want.
