@ JorKadeen:, allow me to second that thought. While it is fine to suggest changes on a talk page, be careful to not edit articles for which you have a conflict of interest. Wikipedia is not here for promotion. 20:08, 23 December 2020 (UTC) reply

My apologies. I shall not make any edits until the deletion debate has been resolved. Then, afterwards, I will either post suggested changes on the talk page or using the COI noticeboard. JorKadeen ( talk) 21:47, 23 December 2020 (UTC) reply

The article names them "Pure" and "Impure" and yet the official website at this time refers to "{}" and "IO" respectively. Nbrader ( talk) 17:54, 10 February 2024 (UTC) reply
