If I were them, I would now pay more attention to tasks in the test network, which, like bounty, does not require financial expenses.
I want to know how the test network thing works. Please can you tell. Does it involve some type knowledge and skill to execute? Am interested if you can direct me what to do.

The tasks in the test network are very similar in different projects and having completed several tasks in accordance with the guide, it will not be difficult for you to perform them in the future even without instructions. You can use the manual for their execution -
