Please note:
Any swimmer who wishes to be ranked by their Country of International Representation for Home Nation meets this summer, rather than the default of being ranked on the basis of Country or ranked club is required to email HNMeetChoice@swimming.org in line with the process outlined in the article which went out at the opening of the window:
http://www.swimming.org/britishswimming/news/swimming/summer-championships-window-is-set-open/23452[1]
The deadline for people to change from the default position in this way is 30th April 2015.
