I think it should be #Mastronauts, with an 'r' - it makes a more complete compound blend that way. But either way I love it, & #Trunkies or #Tuskies are great as well!
To affinity, & beyond!
dBu_fs@daltonedwards I have abbreviated it to "#mastos" but that does not sound too clever. #Trunkies is my favourite but yes, I should think the common word is #mastodonians...
(mastOS would be useful when @Gargron takes over the free universe :-P )
