In Thunderbird: Tools -> Account Settings -> Account Actions, Add Other account. Select Newsgroup account, enter name and Email. For Server Name use news.gwene.org, account name name it whatever you want.
Now right click on the account you just created -> subscribe. You will see two newsgroups in there, expand gwene -> gwene.com -> follow this down until you find gwene.com.rhino3d.v5, you should them be able to subscribe to forum and activity.
Now that I try and do this again, I can't seem to expand gwene, not sure what is going on.
Ok, it looks like all the posts are showing on "activity".
I don't know what is the "forum" link about.
