That would rock!!

I don't think the HTML would be too heavy, but it could get pretty nasty on
the web browser (depending on how many buttons there were per article). I
seem to remember the Fibblesnork LEGO Survey pages (which each have out 100
radio buttons) taking a really really long time to display on non-beefy
machines, and even crashing older browsers from the memory usage in Win32.
But this would probably only be a potential problem for pages with multiple
articles per page -- i.e., huge threads or long full-view ranges.

I was pleasntly surprised to discover last year that they both were smart
enough to make the Tab key bind the radio button and text together in Win32
automatically if there's no intervening foofoo, but I now I can't recall
what that foofoo was. I think it had to be regular text and not a tag, or
something like that. It was tricky to get the tabbing to work right for
Win32 on the member sign-in page:

(Tab key doesn't work the way it should in NN for Linux. :-(

Hadn't thought of that. Hrmmmm.

I was hoping the explicit + sign on numbers might help. +21, +83, +7, etc.
By the time it's obvious to someone that the numbers go up to +90 and above,
they've already seen a couple -20's, etc.?
OTOH, making the range "0" to "100" instead of "-100" to "+100" would nicely
eliminate the need for the positive/negative sign!

Well, if you grow up in Minnesota, yer usta hearing temperatures like "minus
forty" (bad) and "ten above" (good). :-)
Most movie rating scales are what?-- 0 to 4, or 0 to 5, sometimes with 1/2's?
Then there's the two-thumbs-up (+2) and the two-thumbs-down (-2).
(I get a big bang out of Mr. Cranky's[1] inverted scale, BTW... :-)

OK, ya, good point!

Me likee. Could even have as few as 7 or 9 radio buttons.
