How to add a page to a specific menu?

I have created a page on Curating Diptera. I thought I was adding it to the Resources - DF membership area but it has not appeared there. so where is it and how do I put it in the correct location?

Hi John, since your text was quite short I've just added it to the main members' page for now. If needed we can set up a sub-page later on. DF members who are logged in to the website should now be able to access it via the "Resources" menu under "DF membership area".
