I finally got some help to understand what to do....
which was to create a .conf file and
copied (while adding addnode: in front of each)
the numbers provided....
thanks for keeping in mind that more and more ordinaly people
are jumping in crypto world and are not skilled as many of you are
Keep up the good work!
You should add
addnode=
in front of each line, instead of
addnode:
!
Those numbers are regular IP addresses, btw. To be precise - IPv4 addresses with ports in "IP:port" format.
