 And we mentioned collections just very briefly. And what OSF collections are, is like with those registries we mentioned earlier, these are communities that want to aggregate OSF projects. So that same workflow we were just chatting about that are related to their subject areas or their communities. So as a user, if you've developed an OSF project that is public, you may want to, in this case, it's about ultrasound research, you can add your content to this collection, the focused ultrasound folks moderate, of course, the content that would be available in their collection. So, but if it's relevant and strong research, they'll include it in the collection. So a good opportunity to explore the collections that are available here and see if any of them are relevant to your work you might want to submit to.
