I couldn't find a page to submit suggestions. So here are some:
1: A page with an easily found link to submit suggestions. 😀
2: Add the <STRIKE> HTML pair to the allowed list of HTML. It's a form of emphasis useful for a wide variety of posts.
3: Make the indication of the <ABBR> HTML pair more obvious. On my monitor, the dotted underline is nearly invisible. I use it to provide expansion of (duh) abbreviations, such as FCC (👈 hover your pointer over that, presuming you're on a computer.) There's just so much jargon in today's world, often unfamiliar unless it's in your own wheelhouse.
4: Add an optional "About Me" to the user page. It's nice to learn a little about your fellow posters, if they're willing to share. Of course this would need to be used judiciously, but that's true of every post made anyway, so... yeah. I'd use it. 4b: If a somewhat thumbnail-plus sized image was allowed there (as the site is running on its own hardware and storage is insanely cheap... I'd donate to buy a drive if that was needed for image storage), I'd post a pic of my favorite guitar in conjunction with remarks about my love of playing music. 🎸
5: On the main page, a link to a "Typo/spelling Tip" submission would be handy. I saw the "we don't strive for perfection" note WRT the editors, but perhaps it would be easier to just go after the low-hanging fruit if tips were easily caught. There's little downside to a more professionally edited presentation, as long as it's not all that difficult to achieve.
6: On the "Preview Submission" page, the "Allowed HTML" list is not present. It would be useful if it was.
A bug: The "our Team Page" link on the right of the main page is dead: http://fah-web.stanford.edu/cgi-bin/main.py?qtype=teampage&teamnum=230319 [stanford.edu]
Of course, other suggestions would be awesome as comments here until/unless (1).
