My first italki session

I have just had (present perfect tense)  my first session in on (1) i Italki (2) . My teacher Eva was very nice and if you want to learn Spanish, I would recommend that you have a look at her profile.

1. ON + Names of the websites 

2. Websites are always capitalized 

Really nice job, keep it up :)
