Actually I see it used quite often and assume it's acceptable, I just needed a legitimate question title. Anyway my question is whether the familiar "omg" (Heidita, are you reading this?) would be "adm" en español.
Can texts/accronyms be used in comments?
I think you will find your answer here.
One cannot post acronyms properly in comments. All capital letters are rejected as shouting.
You can use any kind of abreviations in comments, yesero, it does not allow all caps though, a nuisance when you want to use acronyms.
thanks for asking
