Verb conjugation of "discipline" in English

I have contacted you 12 months ago to propose your school's inclusion in our language school directory. I wanted to inform you that our site achieved high positions in search engines last month.
We can help each other with these language studies, this is also the main purpose of Vocabulix. I have already got in touch with some other users. I can speak Italian, but my grammar is weak.
How long have you been practicing Spanish using this site and in which lesson are you now? I am now at vocabulary lesson number 3. It is still hard for me, but I'm quite new here and need to get better.
