If you click on their "Track" you will see all the threads they have posted and replied to, as well as all the recipes they posted and replied to. These are all mixed together and appear in chronological order beginning with the most recent activity. I'm hoping Ray will soon fix it so personal recipes are all together on the profiles, or at least so we can do an Advanced Search by recipe creator.
Click here and check reply #8 and #18 for some tips on sorting recipes. If the member you are looking for is very near the beginning or end of the alphabet, sorting from the general Recipe tab may be easier.
