Something for the new BOD to consider. I have been monitoring/lurking AMSAT-BB for years, and still have to go to the archives to read a thread, cut and paste an e-mail to contribute. I still have not figured out its clunkiness. It may be a barrier to new tech types. I am old school and it seems archaic to me.
I am using Groups.io and I am the owner/moderator of two mail lists over there. ICOM-IC-970@groups.io and ICOM-ICR-9000@groups.io. (Welcome aboard if interested)
This is a very flexible system and has both an e-mail and web interface. It was designed to replace yahoo groups which declined into self destruction by yahoo. For my purposes, they run themselves.
I recommend considering it for AMSAT-BB.
Initially there will be some noise from folks in bandwidth challenged areas, but once they read the instructions and set their accounts appropriately it will work fine.
My accounts are free. For a very large organization there may be a subscription cost. It may be possible to have the archives converted and embedded into the list. If not, they can be stored in the files area or linked to their current location. If the change is made, be sure to redirect or block new submissions to the old system so there is thread continuity.
Feel free to subscribe to mine and check out the features.
