The ticker for NEM needs to start with an X. The possibilities are XNM, XEM, XNE. Of these, I really think XEM looks a lot better. Other people on Trello thought so too.
Thanks for the post jabo38, this is an important question for NEM.
Maybe we should start a poll so everyone can express their opinion.
Personally I like both XNM and XEM.
I am not sure how XNM could be pronounced. I prefer XEM because it could be pronounced "ZEM," which sounds kinda cool

Also, the N in NEM means "new," but in 100 years, will it still be considered "new"?
Phasing out the "N" wouldn't be a bad idea at all.
I think XNM visually looks better, but have to agree with you on all other points.
