I wasn't aware of any existing X Reflector list, so I created one here: xrefl.net
The page gives an email address to notify me of any additions, requests to remove, or other changes requested by XRF owners/admins, but I will also follow this thread. There are also sections to list regularly scheduled events (i.e. nets) and special events.
To XRF owners/admins: If your XRF is not listed and you would like it to be, please me know and include an operational dashboard URL, the hosting station or organization, and the organization's web site if there is one.
I'm the sysop of Italian Reflector REF080, I ask you to activate the ref080.dstargateway.org in DPlus_Hosts.txt file (remove #). Many amateur radio contact me because they can not connect because of #.
