Hello, Serg!o. I'm sorry, I do not know if this is the correct way to message someone on here. I was wondering if I could have your permission to print out your "Conjugaciones de correr" file and use it as a teaching aid and reference to help tutor a student. I was planning on printing it out and labeling "Past", "Present" and "Future" and feel that it may be helpful to my student. Please let me know if I have your permission. Gracias.
