Yes, surely I would give you the details where you can post your knowledge and let it be known to the world.
I am mentioning some sections here for the help as you asked and you will not a clear idea unless you see them and post one or two in them, after this you would yourself be in a state of inventing new things on this site,
1. If you like to submit some practice test questions, you may visit the page as follows and ask for the permission over there. By reading the forum message you will get a clear idea about this section,
This section is intended to post the self made questions by you and if they are approved you will be credited with the respective amount also.
2. There is a section called school section where you have to submit the schools that are given to you. Primarily this work was started from the schools of USA, the link is - http://studyvillage.com/forum/320-Schools-section-post-get-paid.aspx
In this also the credits that are offered are according to your posts i.e., if you just post the details about school, you will get around 2Rs. but with additional details you may double the amount also and there is one interesting thing from this section of paying 500/1500 according to your work.
3. You may submit the paper craft items that are done by you in either descriptive way or through a video and can ask a permission over here - http://studyvillage.com/forum/391-Make-paper-craft-other-activities-for-children-get-paid-Rs-per-post.aspx
4. There are various other sections where by seeing them once, you can get the idea like previously submitted resources in http://studyvillage.com/resources/Category5005-Printables.aspx link.
This helps far better and even then you may see the other sections that are available on the top page of the Studyvillage tab.
