Don’t wait for an email response.
Call the regional director and ask.
It’ll be too disorganized if people just drop in to help.
They need to know who is present and will want to know who you are before they’ll be ok with your attending.
You can offer to help with your particular chapter (your local community). Let the director know you are really interested in getting involved with kiruv and because of time/travel constraints, can only work with your local region. Be available even to do office work voluntarily to assist. It might help you get your foot in the door.
