Folks have been sharing a few external links here and there, so here's a dedicated thread for that. When you post links in this thread, your comment should include the following:

• the link(s), of course,
• description of what the link goes to,
• and how you think that site or page will help this community.

Please try to consolidate your links. That is, if you have five links to share at once, it's better to share them all in one comment instead of making five separate comments.
