+, - on edit lists
I have been wondering for a very long time: in a list of edits like List of living supercentenarians: Revision history, can you please tell me what the positive in bold green and negative in bold red mean? Deaths in 2013 (talk) 05:02, 27 November 2014 (UTC)
 * The number of characters (and so bytes) added or subtracted. Ian.thomson (talk) 05:05, 27 November 2014 (UTC)
 * Bytes, not characters. For example, this demonstration edit in the Sandbox changed six instances of "a" to "á"; the number of characters is the same, but "á" in UTF-8 requires two bytes whereas characters that come from ASCII, such as "a", require one each; so if you check the edit history, you'll see that it shows +6 bytes for the change. --65.94.50.4 (talk) 06:31, 27 November 2014 (UTC)
 * Us old-timers are used to thinking of bytes and characters as being equivalent. At some point you run out of bytes before you run out of characters, necessitating an extended character set such as UTF-8. ←Baseball Bugs What's up, Doc? carrots→ 17:24, 27 November 2014 (UTC)


 * At the top of any Revision history page, follow the link "For more help, see Help:Page history". The help page has a diagram and explanations of the various parts of the history page. Number 15 explains the + or &minus; numbers and says "See more at Added or removed characters". That page says numbers above 500 are bold. --Bavi H (talk) 15:44, 27 November 2014 (UTC)

guide please (PENICILLIUM QUANTI allergy)
You are doing great and appreciable efforts in mentioning very helpful informations all times. Kuldip Aggarwal — Preceding unsigned comment added by 70.75.72.55 (talk) 16:05, 27 November 2014 (UTC)
 * Reasons of high IgE AB PENICILLIUM QUANTI allergy.
 * Effects of this high allergy with further testing and treatment.


 * I changed the title into something useful. StuRat (talk) 16:11, 27 November 2014 (UTC)
 * Google does not recognize "Penicillium quanti" (apart from this posting). Penicillin, Penicillin drug reaction and Penicillium may be useful articles. Tevildo (talk) 23:55, 28 November 2014 (UTC)

Do Southeastern USA Alligators leave half-eaten carcasses at water's edge?
I was wondering about a particular evidence of half-eaten opossums and the like lying at the edge of ponds and rivers (I live in the Southeastern USA). Do gators leave those lying around to attract new victims? If it's not alligators then what is doing it? Thanks. Zombiesturm (talk) 21:22, 27 November 2014 (UTC)
 * Not sure about the examples you cited, but this article seems to indicate that they've been observed to use sticks as bait to lure birds.  bibliomaniac 1  5  04:57, 1 December 2014 (UTC)
 * Are you suggesting the half-eaten food is bait? ?μηδείς (talk) 02:09, 2 December 2014 (UTC)


 * Could be Americans. They've been known to trap roughly 100% of everything, intentionally or not, and on average, eat half. Of course, FOX News may be biased.
 * According to CNN, Florida alligator trappers kill the ones on land first. For up to $60 a foot, you can bet they're being coaxed by anything that might make them easier prey.
 * Could be a lot of things, though. Just because it's beside a river doesn't mean it was killed in or by one. Dogs and cats often leave half rodents (almost always the back half, I find), and probably don't differentiate for rat-like marsupials. Then maybe a bird grabs it, gets shot and they both land in the water. Maybe an entire possum went for a swim and got propellered in half.
 * Alligators would be low on my list of suspects. Half a kangaroo, maybe, but possum are for swallowing whole. InedibleHulk (talk) 12:01, 2 December 2014 (UTC)
