I find the easiest way to find a project ID is to do this:
- In the top search box, type in some letters of the project name.
- When the project you want appears in the dropdown, hover over the Observations option (hovering over the About option gives you the named URL).
- This gives you the project ID number in the URL that shows in the bottom-left of the screen (FF, Brave, Chrome - don’t know where it shows in Safari).
- Note down the number (using a piece of paper and a pen - this may sound primitive ;-D).
- Then search for the next project and note down that ID number.
- Once you’ve got them all, add to the search URL you’re filtering for.
- If you intend using the filters again in future, bookmark the page so you don’t have to go through all of this again.
Hope this helps :-)
Just by the by, a tip for finding user IDs on the people page - if you hover over the picture (avatar) you get the name, and if you hover over the username you get the ID (or it’s the other way round).
