Know the italki...
This is my first time in this website. ('It' is ok but 'this' sounds better in this context)
My English teacher suggested this site to us in his reposition[?] class and I accepted his suggestion.
I am still confused about configurations (? - not sure what you mean by configurations in this context) and when is the best way to use them.
My English is basic and my Spanish, too.
I hope to find many people to teach me.

General Notes:

i). Languages & countries always start with capitals in English (I know they in some other European languages)

ii). 'Many' is used for things that you can count. Much is used for things that you can't count. e.g. I have many coins (e.g. 100, 200 etc). I don't much money (you can't say 1 money, 2 money etc)

Also note that 'a lot' can be used in place of 'many' and 'much' (although I would consider it a more informal use of English)

[Welcome. First suggestion - the teacher teaches and the student learns from the teacher.  What are some examples of configurations that you are having trouble with?]
