Kong players cannot help with FB's post request, FB players cannot help with Kong players help request posted to their profile either. This is an unfortunate restriction as the platforms are pretty much different with the URL they share to their timeline/profile.
If you have a really good friend on Kong that you want to help each other's build progress, technically there is a work around.
When you open Facebook's help link, the browser URL will say something like
https://apps.facebook.com/time-world/?plid=XXXX&plra=YYYY&refpid=help&taid=ZZZZZZZZAnd Kongregate's help link, the browser URL will say something like
http://www.kongregate.com/games/playmage/time-world/?kv_plid=XXXX&kv_plra=YYYY&kv_refpid=help&kv_taid=ZZZZZZZNote the bolded If you take Facebook's query String parameters are pretty much the same as Kongregate's except the missing "kv_" before them. So if you open a browser window and manually change the Facebook URL into a Kongregate URL by adding the "kv_" for each paramter (or vice versa removing), then you can help with each other's help request.
