Yes, you make another datatype called “Like” With a field for Post (Post datatype) and a field for User (User datatype) When they click like it creates a new Like, sets those two fields. Then later in the future if you want to look at all your liked posts you do Do a search for Like, constraint User = Current user, then do :each item's Post Or to get all the Users that liked a specific post, you do Do a search for Like, constraint Post = [specific post], then do :each item's User There would…

You can still stick a number of likes field on each post so you can sort by # of likes
