We have a bunch of ways to stay in touch but if you love a bit of old school we have the Serious Mailing List.
All important anouchments will be covered off in this list and all members can use this list for important anouchments regarding runs or other administrative topics of the club.
If you are not on the CH3 Serious mailing list then you should be.
No jokes, memes or other crap, it is a curated list that only shares hashing related information.
If you want to sign up there are two options:

1) Send an email to ch3-serious+subscribe@groups.io

2) Visit https://groups.io/g/ch3-serious click on the blue button which leads to https://groups.io/g/ch3-serious/join where you can fill in your email address
