The URL searching confused me a bit to begin with too, but I find it really helpful now!
Basically, when you type in iNaturalist.org/identifications, there a bits you can write after that which tell the website what type of identifications you want to see. If you type in “?user_id=juliereid” after it, it tells the website that you want to see all the identifications that are made by the user (that’s the ?user_id bit) called juliereid. So that will search for all your identifications!
If you only add that bit, though, it will show you only identifications you have made on your own observations. To make it search for your identifications on other people’s observations, you can add “&for=others”. The “&” tells the website you want to do more than one thing, and the “for=others” tells the website you want to look for your identifications on other people’s observations.
So if you click the link…
…Then that’s what it will search for. It’s not immediately straightforward, but hopefully this will help.
You can tell the website to only show you other things too, by adding more bits to the website address (using the whole “&” thing we looked at earlier). This link is a bit confusing too but it does help explain all the other things you can do quite well: https://forum.inaturalist.org/t/how-to-use-inaturalists-search-urls-wiki/63.
There’s not a simple way to do any of this yet, like there is with observations, but hopefully this sort of workaround will help you until there is. :)
