All officials should have been invited to the officials comm and given access to the right communities, reply to the post in the officials comm to get any passwords you might need.
I've not had a chance in all cases to clear out of the old mods. For each community the people who should have maintainer status are:
Yourself and your comod
Any associated account (i.e. slyth_prefects in cunningfolk)
The minimod account
The mod account
Any problems reply here :)
