I need some help with MyLot Tasks please...

When you open a task that interests you and you scroll down to the bottom of the information, as Guitarpunk said, it's an orange button you're looking for that says "accept this task"... it's on the right hand side of the screen. Once you accept a task, you have to go to your "in progress" tab to work on it. Once it moves to "in progress," you are able to input information into the field(s) and, below that, there are two other buttons - "submit" and "forfeit". If you can't do a task you accept, for any reason, you have the option to forfeit it. Or, if you don't complete the task within the time limit that is provided, the task becomes "abandoned". You'll see a tally of these actions on your dashboard, along with your other general information. Hope this helps and good luck with the tasks! :)
