Does anyone know any site where we can earn money in writing?

Try Textbroker.com and Ecopywriters.com. At Textbroker they pay twice a month if you have at $10 and it is very easy to make that. I have $20 to $30 in one day there. Ecopywriters I have made $30 in day there also, the only thing about them is they are slow paying, but they do pay and they pay more per article than Textbroker. You might also what to try Associated Content. They pay upfront money for articles that they accept.

I think Myot is the best and the easiest so far!!! But among others there are Squidoo, Bukisa, HubPages, associatedontent...I believe these are the most popular so far. But of course they require articles of qood quality.

Yes here is lot of offer from Freelance Job Provider for paying you against wriring articles on various subject. It is not scam - just get the work and take the money to your account or paypal - 100% perfect and honest income from work online and at spare time. http://www.getafreelancer.com/affiliates/asianco/

You can check out sharedreviews. This a product review site. I had been paid twice by this site via paypal. I also write product reviews at dooyoo uk.but i only earn amazon voucher from this site because I live outside UK. however you can send you can send your earnings directly to your bank account if you are from UK. I also publish few write ups at triond but I'm not earning much from this site

I think you'll like Triond and AssociatedContent for writing articles and other content. Some other sites for writing articles are Bukisa and ContentCaboodle. Helium pays better if you have your writing and rating stars. I think oDesk would be a good place to work with because you can get different kinds of publishing work. It is a freelance marketplace and they pay you with an oDesk debit card. You can get proofreading, editing, reviewing and writing work. You can also get other kinds of jobs. You can also get free certifications and certification tests. That's at www.oDesk.com. It is all free.
