Are we allowed to send links to Archive.org if the contents are appropriate? Im making a project, and uploading something, but the text may be too small for some readers and I’m wondering if I could send them a link to view the images.

Yes, you are.

The same applies to most other websites.

As long as they’re approved and are for all ages and appropriate for Scratch, then yes, you can.

And since archive.org falls under the “for everyone” status, i think it's allowed.

hope this helps!
