The first

Hi my friends!
Today I feel a little bit different. I decided to start an account on this page because I think it will be very interesting to improve my English. at the most. (I’m not quite certain what you mean by “at the most.”)
If I write everyday every day in English and you correct my writes writing, (or, “you correct what I’ve written") it would will be easier for me to learn this language!
Thank you so much! I'm waiting for your corrects corrections!! (You could also say, “I’m awaiting your corrections.”)

Welcome to iTalki Victoria.  Everyday versus every day can be challenging -- however, when you intend for something to be done daily (cada día) you want to use every day.  If a sentence doesn’t make sense using “each day” in place of “every day,” then you can probably use “everyday” and be correct.  [Cada día = every day; Cortidiano = everyday].  I hope this helps.
