(Hello

My name is Tomas. I am a Spanish student of {Englhis}?.I do not know what do you mean by this word! I am a computer science teacher at a secondary school. I want to practice English.

My colleague introduced me this website as a good place to learn a foriegn language.)

Welcome Tomas. You are a new student and I am a new teacher on iTalki.
I want to add another correction to your writing and explain the difference between "practice" and "practise" as used in the UK and Australia.
Practice is a noun as in "a medical practice."
Practise is a verb so it's better to write "I want to practise English."
I hope that's a useful tip and good luck with your studies.
