I actually emailed CRC only last week about this issue, because of losing the list when the cookies were wiped, and also because the list didnt follow me around the various computers i use.
Got a reply, apparently theyre aware its not an ideal situation, and are looking to introduce a list linked to your crc login, so guess its then always available anywhere – however, This wont be released until a new platform update, unlikely to be until the new year now.
if you know the cookies are about to be cleared, just send yourself the ’email to a friend’ list, least you wont lose sight of all the components you are tracking until the price drops!
