I sent an email with the following sentence.

The meetings will be discussing this early next week.

Why do we use

• will be discussing on each other instead of will be discussing? I don’t know the purpose of the future continuous here, or the general purpose of the future continuous tense.

• Should we use will discuss this matter or will have discussion on this matter (I guess that was a mistake to use will discuss on here)?

What are some key points I should be concerned about while writing this article?
