Hi Dani, and welcome to WW
The best way to make the most of this site is to get involved. Have a mosey round the groups and see which ones match most closely the sort of writing you do – bearing in mind that you can only join one while you're on the free trial period.
Read what other members have uploaded (click on the Archive button at the top of any page), and see what sort of comments have been made. When you're ready, upload a piece of your own work and ask for feedback. Keep it short, though – we usually suggest under 2000 words to start with.
Have a look at the forums and, if there’s anything you'd like to discuss, or anything specific you need help with in your writing, start a new thread.
And don’t forget Nik and I are here to help if you get stuck.
