Troop 160 uses a members-only Google Group for communication and sharing:

Troop 160 Members Only - this list is curated by the troop.
Members (Scouts/parents/guardians/adults) can also request to be added by first logging into a Google account and clicking the link.

In addition, we also have special email groups for high adventure trips such as Sea Base, Matagamon, and Philmont.

Yes. See how email works with Google Groups.

No. But...If you have a Google Account, you may search & browse a Groups topic archive and you also get access to Troop 160's ebsite Community Access where Scouts and parents may contribute to this website.

You can create a Google Account very easily for free.

You can keep your existing email and still open a Google Account very easily.

Troop 160 Boy Scouts are not required to have a personal email address but each registered Scout should have an email address he may be contacted at, even if that is a parent's email address.  Parents of younger Scouts may choose to just use their family email address and subscribe to the T160 group that way.

Members of the Scouts and Adults group may find that new topics and topic discussion causes a lot of email.  When it comes to Boy Scout activities - there can be a lot of details and Troop 160 is big. Google Groups makes it easy to configure how much email (including no email at all) you receive from the Group. Maybe you just need a daily or weekly digest; or perhaps you just want to browse the tropics through the Group's web page regularly.  Sometimes, it may be helpful to temporarily reduce stop or digest the email you are receiving.
