$10 a month seems like a little too much trouble to go through... of course I don't know how many of you are from places where the cost of living is substantially lower than mine.
You can try, but with only 200+ posts you probably won't get much for it. Better to wait until you have 1000 posts before you start selling.
There is nothing wrong with selling your avatar space. I receive a monthly stipend of $45 from the Pumpkin Western and North-eastern Distributors (PWNED) for the use of my avatar space. Those pumpkin people sure pay good money but I hear the zucchini and cabbage people (ZEECH) may be paying more come next year.
Me, personally? Hardly any for the first few months that I was here... Then I started out slowly when I did start posting... Now I am up around 30 or more per day.
