New Administrator

I am about to take over as my society's new administrator (Lee) as the present one is to step down (Ralph),i am at present using his login/password typing this but struggling to find the relevant section to edit/change the details.I did edit his personal details but then realised i would take over his handicap and previous history.I would be most grateful for any advice. Regards Lee

Can you get Lee to email in and I'll move over the group ownership.
