Textbroker writers must request payout to their Paypal accounts to get paid. Currently, there is a minimum payout amount of $10, meaning that if you don't have that much in pending pay, you must wait until the next payout date.
Of course, many clients who use content sites are on a tight budget, and some don't deal with this very well. It's downright insulting to see clients place orders for 2-star pay, then make it clear they expect 5-star quality. You can generally avoid taking these orders by reading the descriptions carefully-if they seem too complex for the pay level, simply pass them up. Some orders also specify too many keywords for the desired word count, to the point that if the keyword density was met, the article would be a bunch of senseless rubbish. Avoid these as well.
I am extremely pleased with Textbroker, and even though I've been accepted at several other writing sites, it is still one of my favorites. I check the site daily for available jobs and recommend it to everyone I know who is interested in getting into writing.
The next writing site I joined was eCopywriters. More on that later.
