My first visit

Hello everyone, I am new here. And I (avoid starting new sentences with 'and') have no idea about this app (this last phrase is ok however 'I don't know anything about this app' would work better), however, I found find (present tense - you could say 'I have found' also) it quite interesting. My purpose in joining this site is to improve my English writing and speaking skills. So, welcome to every person who shares my aim. Thank you in advance!
