The students will need to sign up, but I think if we are using it regularly, it’s a good one to keep. You can create groups too, so you can set up group canvases that you can invite the students to.
I’ve used Lino a few times now as ‘working boards’ for topics and as another way to get kids to share their information. When I asked the students for their feedback on this, they said they liked it and found it easy to use. They said they liked it as much as Padlet, so in the end, I guess it’s up to teacher preference! I think it’s a useful tool to introduce to the students as they can then begin to use it themselves to set up group canvases for project brainstorming, or for personal project planning.
