What HTML tags are allowed on the three main Metafilter sections? (I dare not experiment for obvious reasons.)

I doubt Matt has them all memorized, so it would probably help to list the ones we know of so far.

Is blink disabled? I tested the ones I hadn't tried in preview (at great fear of actually hitting post by mistake) and nothing happened with that one.

span is dropped, iirc (at least in the main pages; anything goes in the user pages, afaik)

It works in Firefox but not IE.

I did find a problem with <code> and <pre> when I was trying to post snippets of code in this AskMe posting.

A weird "br>" would get stuck in a line... some post-processing thingie that Matt probably wrote. I think it's busted...

This seems a good place to post this:

To write the ampersand in &nbsp; one has to use &amp;
So to write &nbsp; you would have to write &amp;nbsp; .
Note that when you hit preview your & will be eaten, so you may wish to use copy/paste accordingly.

Add <acronym> and <abbr> to the list. I use those all the time.

Hmm...Several of those entries above were doubled up.

mcwetboy, thanks for the acronym and abbr codes, I wasn't aware of those. Kinda cool.

So, with those added, and the doubled up ones removed:

At least until someone trumps him by taking his idea and making an ASCII Frogger screen out of it.

Instead of talking about what I allow, I approach the coding by allowing all, and merely blocking truly nefarious things while trusting users to act in good faith.

So you can do anything on the front page, but the following is stripped out:

paragraph tags, since I don't want to encourage people to take up too much vertical space

script tags, since there is very little chance outside of cross-site-scripting hacks that it would be used.

inline styles, also for various cross-site-scripting hack reasons.

Pretty much everything else is allowed, but that doesn't mean you should use it all.

sometimes the sun reflecting off the sandbox would hurt our eyes,
so we'd dig up these rings and play with them for a while.

you'd have to wrap the thin curly metal bits around your finger
and then you could spin it so fast
you couldn't tell which way it was going and which part was where.

diary entry: the marquee tag is interpreted very differently in different browsers. In firefox on a PC apparently the browser won't interpret two marquee tags on the same line, so an artificial linebreak is inserted. (thus april 20-22 are broken and the sandbox and loom are double-spaced). In explorer on a mac the height variable is interpreted differently (so the april 19th junk post before the sandbox post is broken and odinstream's post looks like just a line of numbers scrolling smoothly upward.)
at work i've been using safari on a mac:
in safari on the mac a linebreak between two marquee instances doesn't introduce an additional space between each line, so the sandbox is more highly compressed and the loom feels much more like interlocking \/\/\/\/\/\/\'s. all the rest are single character-width marquees lined up next to each other. explorer on pc is closest. i'll have to test firefox on a mac next week.

oh, the fishtank looks nice in firefox/pc. in safari/mac, there are two marquees per line and so the fish collide and the brown bar looks like a mistake.
