the new task thing...

It appears that mylot posts the new tasks in the early evening (eastern time)...at least that's when I've seen a larger quantity of them. Each task lists how many slots are available out of the original total mylot wants so it's a good idea to check often. It's not possible for you to make up your own tasks although that would be a good idea! The rules are to basically read what each task involves and follow the directions. Some of them are writing tasks and others are different.

I do believe the tasks will be constantly changing. Each task is only available for so long, so once they're up, I do believe MyLot will post new tasks. I don't know exactly what you mean with "making your own task." You can't really make your own task. They're given to you and you decide if you want to write about the topic or complete the task and go from there.
