MERG (Model Electronic Railway Group)
Several posts on this forum have referred to MERG CBUS as a layout control protocol (perhaps most popular in the UK where MERG is headquartered), and several people have referred to the many electronics kits made available by MERG. I joined MERG about a year ago (it is a hobby organization with about 4000 members) and have much enjoyed participating in their Zoom meetings as well as reading their quarterly journal and “knowledgebase.” They have said that Zoom meetings will continue indefinitely as it has boosted their geographic reach and made it a more worldwide organization. DCC of course is core to many discussions. Just passing this on in case others may also find this group of value. See https://www.merg.org.uk/.
