Hey @jywarren, I need some help to understand exactly what you need us to do here! Your comment:

[...]change the sorting of the results in the API to most recently updated people... so changing this line from this instead of this --- a good break-out issue!

Well, the methods return profiles based in different parameters. If I understood correctly, textSearch_profiles method searches for profiles with matching usernames. And textSearch_recentPeople method gets X number of latest people/contributors - with X equal to srchString - optionally we can also filter the search by tag. So, I didnt understand what you mean by ΅changing this lines..." if the methods are different.

By chance, is (textSearch_profiles returning users sorted by users with more recent activities) what you would like?
