[b]has been changed (definitively) into:[/b]

[code]if(w3appendevents.indexOf('w3allmchatif') == -1){
//if(parent.location.href.indexOf(wordpress_url_page_forum) > -1){
parent.w3all_ajaxup_from_phpbb(w3appendevents);
//}
}[/code]

This now handle and correctly fire, events into phpBB, passed to WordPress.
I'm sorry that i've forgot this aspect, but let say that it has been also forgotten on this online example where now correctly applied. When user login or register in iframe, it correctly redirect and update WordPress also.
