I just checked now and ir and venir both give wrong results
I will fix this as soon as I possibly can.
1st person: yo voy (I go/am going) yo vengo (I come/am coming)
2nd person: tu vas (you're going) tu vienes (you're coming)
2nd person (formal): usted va (you're going) usted viene (you're coming)
3rd person: el/ella va (he/she is going) el/ella viene (he/she is coming)
For the second and third persons, I only put the singular version, not the plural.
