Well I've been accepted by Helium and Demand Studios and have written a couple of articles for Helium and tried to write one for DS but apparently the review I made to my bio hasn't been cleared yet so I can't write anything yet. So allow me to tell you what I've found.
Helium seems easy to write for, both of the articles that I wrote have been accepted but then I don't see how the aren't. It was like you write, you post and it's there. As yet I haven't been able to work out how you get paid. My friend who does this type of writing to pay the bills since she lost her job said the same thing so she doesn't write for them much so I might follow her lead on that one for now.
As for Demand Studios they pay regularly and quickly but I have been struggling with the articles that they want. One of the gems yesterday was Beer Faucet and Shank Assembly. What????
Needless to say I feel like I hven't got very far on the sites themselves but things that I have read on there have started trains of thought for other things.
This internet writing lark may be the future but give me a page you can turn any day of the week.
