Hi Susana,
A warm welcome to the Colony and hope you enjoy it here.
There's plenty to do and we have lots of people happy to give and receive advice on works in progress. You'll get the most from the Colony with a two-way exchange and you'll be pleasantly surprised how beneficial offering critiques on the works of others is for your own work.
Litopia is a friendly and supportive community. The best thing to do is dive right in. You'll find a very helpful intro here
How to guide which will point you in the right direction, and the Writing Workshops Directory
WWD is a great place to road test your opening pages, chapters, blurbs & synopses etc.
If there's anything you're unsure about please drop me a message and I'll be happy to help.
