Welcome to Wattpad !!
I'm glad you decided to join this site as well, I hope you'll come to like it as much as I do. There are quite some amazing people and stories on here.
To help you get started on Wattpad I suggest you take a look @Writing-101, there's a guide that helps you update your profile, tells you how to upload stories, create story groups and how to add Book covers. [Feel free to leave any suggestions on how to improve]
If there's anything else you need help with, just let me know, I'd be more than happy to help you out with whatever I can! You can also find the other Wattpad Ambassadors here: @WPNinjas
The new Wattpad support page is also a great way to get answers, help, or let Wattpad know about any suggestions you have. http://support.wattpad.com/home,
Try the Discovery tab and/or Wattpad shuffle (which you can find in the right hand corner at the top of this page) when you're looking for new things to read. Make sure to pay a visit to one of the many Wattpad Clubs too where you can promote your work, get suggestions from other Wattpad members, talk about random things and make new friends (http://www.wattpad.com/club/22-newcomers )
So, all that's left to say is: Have fun on Wattpad!
