More than 1 person to Sign in

I have a Pro account and run two AA Meetings a week from my account.

I am an elder of 84 and forgot to sign us all in two time in the last few months!!!

 That would mean 12 or so folks not getting to a what may be a life-saving meeting.

I also use my account for Family once a week and a class on Saturday. I do not initiate these meetings...just the two AA ones.

Can someone help teach us how I can have two other people (one for each AA Meeting) sign in on my account if I forgot or become ill?

They will not use the account for any other reason.

Thanks in advance for any help with this!
