The amount of tasks, their value and whether or not they are available to you is all dependent on CrowdFlower (the task company).
We have no control over if or when they will show a task to you, so there is really no point in asking us for more tasks. Please don't send us tickets with such requests.
We were advised by Crowdflower to have you keep checking the task page each time you login as new tasks come in all the time. However, within a month, several days with very few tasks available, or none at all, are to be expected, so keep checking back.
