The Question on the pronoun "Os"
This question revolves around the grammar rules for combining direct and indirect pronouns with the infinitive verb form.
Can the pronoun "Os" be added to the infinitive like the all the other direct and indirect object pronouns?
Example. Van a decirte la noticia.
Van a decirnos la noticia.
Van a deciros la noticia
`
I have never seen "os" added to a infinitive nor to a progressive tense.
enviar + os = **enviaros** enviando + os 42**enviándoos**42
Thank you for your help!

If you have never seen it, then you need to read more things written by Spaniards.
What is interesting is os and the commands, not the infinitive nor the gerundio.
vosotros affirmative command....decid+os=decíos
concerning the "oo" in diciéndoos
I have never seen any exceptions in a grammar rule concerning direct or indirect object pronouns concerning the use of os (except with vosotros commands which only concerns the command's spelling).
La forma de vosotros es muy común en España pero los otros hispanohablantes no se lo usan. Si viajes a España sería importante aprenderlo.
The vosotros form is very common in Spain, but it isn't used by other Spanish speakers. If you travel to Spain it would be important to learn it.
Well to answer your question simply: yes. These nice people have given you good information too though!
Don't be too surprised if you hear vosotros outside of Spain, it is possible. I've never heard anyone not from Spain say it (except me), but I've never been to Spain and I speak in vosotros every day!
