If you click on the "are you getting paid to post" link at the top of any Forum page, it will take you to the instructions for the Forum posting bonus.
1. You need to have 30 meaningful posts during a given calendar month. I usually have 40-50 posts just in case some of them are deemed inadequate. Posts in the Contest and Promotion section do not count.
2. Towards the end of the month, after you have 30 or more posts, click on the "paid to post" link again. In the middle of that landing page is another green link to the page that asks you to enter the ID numbers of 3 of your posts -- presumedly ones that you like or considered representive of your best posts.
3. On the right side of that same page is a count indicating how many posts you have made so far this month. Right below that is a link that will let you look at all of the posts you've made. In the header of each post is an ID number for that post. As you scan through your posts, select the 3 you like best and jot down the ID number (carefully). Also make sure that you do not go to the prior month when making your selection.
4. Once you have the 3 ID's for your selected posts, go back to the page with the entry form; enter your 3 ID number and submit.
5. At the bottom of that page is a history of the submissions you've made for the Forum Posting Bonus. It will tell you how many days until you can expect payment. Generally, payment is made towards the end of the month following the month you make your submission.
