I don't know about how the uids work. I just know when you make a post, after it posts it just adds it to a list of own posts on your local storage

$(document).on('ajax_after_post', function(e, r) {

var posts = JSON.parse(localStorage.own_posts || '{}');

posts[board] = posts[board] || [];

posts[board].push(r.id);

localStorage.own_posts = JSON.stringify(posts);

});
