How does a task work?

If you see #keyword# where the actual keyword(s) SHOULD be, the task has an error. You can't accept it because you would have no idea how to do it, as you've said. Just let it be and it will be removed from the available tasks section soon enough. New ones will come up soon, I'm sure, and hopefully you'll be able to get one or some to try. Keep checking back to see if anything has been posted and, in the meantime, do read the information that was suggested to you in the response above mine. That way you'll be prepared and know how to go about it all :) Best of luck to you with your tasks!
