My publisher is looking for new authors, so this might be the ideal time :-) Have a look at the following:
Packt Publishing, the publisher of computer related books, plans to expand its range of Silverlight books and is currently inviting inquiries from people who fancy writing a Silverlight book. You do not need to have any writing experience to write for Packt. Anyone who loves Silverlight and fancies writing a book can get in touch with Packt at author@packtpub.com with his/her book ideas. Even if you don’t have a book idea ad are just interested in writing a book, Packt is still keen to talk to you.
