Unfortunately, I think multiple links in your sig makes the TOTAL number of characters >1000.
BB code markup is all the carp formatting info the forum software uses to convert text into
BOLD/Italic/
underlined, font
size/color/
type and the url/img coding for pix and links. There are a minimum of 5 characters for every change, no matter which you use. The 4 total parenthesis and the backslash plus the characters for the change and or formatting: img, url, B or whatever the letters/numbers might be.
Color/sizing and font type are a huge number of characters compared to the others, as does smiliies. On my phone a simple smiley might be only 22 characters colon and right parenthesis
Others are 30+ characters. I suspect beating a dead horse is several more then 2 :deadhorse:
No idea what the conversion is for sig pix into character link, but there's probably a form factor for converting it.............
I deleted all the 19XX from my boat sig links, only saved me the 19 (2 characters) per link, but seemed to help get the total under 1000
