How do you pronounce GNR? It think it needs to be a vowel, or an R.

Some attempts: GRR: Gnu Renames Rust, GAR: Gnu assimilates rust, GER: Gnu non Est Rust (gnu is not rust, but in latin to get an E), GIR: Gnu Isn't Rust, GOR: Gnu Oxidizes Rust, GUR: Gnu Unseats Rust.

pronounces it Gnar or Gener, depending if you are a gif or a jif person.

You can also go for GunsNRoses, but they won't like it and complain. Which might be good for visibility at the beginning.

Or something like "oxide", ferrite, maGNUtite. Play with iron ores or compounds

oxide computing is taken... plus the name game around compound is tiring. I prefer to try rock bands.
