congrats. its interesting that people announcing their income that high usually have a link to a site having to do something with adsense
My adsense income always increasing month after month. I just start actively in online money making about in august/september 2008.on November my earning only USD15. last month disember my earning is USD44. This month is more than USD88. If I will try harder to make it twice, triple or more the amount next month! Despite the economy worsen I believe I will succeed.
Congratulations.. Is it your last month's earning which is being sent or its the current month's earnings till date?
I find these type of postings a waste of time. It would be better if you set out how long you had the site and what you did to achieve that figure.
