Translation of vorhersehbar

I have considered the option to bring my friends from other social networks and invite them to join here. They can develop better language skills here. I'd love to pursue that goal, but I want to write in English.
The easiest way of writing sentences in Spanish and English is to communicate with other people by email or by chat. I found the different time forms quite in Spanish very confusing at the beginning and it was the most difficult part.
These may be linguistic and cultural differences. There are indeed various regions throughout Spain and the word choice is not always the same. It is sometimes hard to understand people from other cities.
