Hammy, not sure about the 15 yr age at this time - I can't find anything to support this, but ya never know it could be in the works as KKm said... however I am certain that for 2008 the age is 16 (or turning 16 in that olympic year). Ivana turns 15 in dec 07 and 16 in dec 08 - which makes her age eligible for the 2008 Olympics... I can post the actual rules in a bit, but here is an excerpt from Wikipedia for now:
"The FIG imposes a minimum age limit on gymnasts competing in international meets. The term
senior, in gymnastics, refers to any world-class/elite gymnast who is age-eligible under FIG rules.
Currently, gymnasts must be at least sixteen years of age, or turning sixteen within the calendar year to compete in senior-level events. The one exception to this rule is the year before the Olympics, when gymnasts who are one year shy of the age requirement may compete at the Worlds and other meets. For instance, gymnasts born in 1988 were allowed to compete in senior events in 2003. This is permitted to allow nations to qualify to the Olympics with their best teams, and to give emerging gymnasts some experience in major competition before the Olympics."

This rule was supposed to change following the 2008 olympics as a no exception rule with the min age being 16 yrs as of the actual event.
