Just a little history for you all.... "teams" have ALWAYS been present in some shape or form. Following this link http://webzoom.freewebs.com/nftac/WF...(725x1024).jpg
you will see that in 1992 there were teams of 15 (GB and USA), though it appears this was later reduced to 9 counting. GB beat USA by 408 to 322 ex 450. The '92 champs were open to 200, though 150 participated. Rules re team configuration have always been a subject of voting by the members countries at that time, and have gone from 4 period to 8 with 6 counting to 8 with 4 counting. At the first "Worlds" in the USA 1991 GB beat USA by 1334 to 1264 ex 1500 (!) So, as for the theory of the World's just being an individual event - I think we can now put that one to bed.

You need two things in life - WD40 & duct tape. If it moves and it shouldn't, use the duct tape. If it should and it don't, use the WD40.
