You're welcome and I'm happy to help. I have translated your comment to English a I don't speak Spanish and I'm going to try to reply in English.
So you publish a post once. After that, you cross-post it. You can cross-post it to OCD, if you have published it in the right community first, not on your blog.
If you publish something in a community, you can cross-post it to other communities too, but please check the community rules first as not every community accepts cross posting.
I hope you understand what I mean, If not, please contact @victoria.bsb, who can explain it to you in Spanish.
Gracias. Ya leí tu post sobre el tema de publicaciones cruzadas, aprendí mucho. Tu aporte es excelente. Seguiré leyendo tus publicaciones en inglés. Aun debo aprender más.
