When anda komen on a profil wall, the peminat whose profil it is always gets a message in his atau her kemaskini about it, but obviously they sometimes don't reply. When anda komen on a club wall, only people who choose to look at the dinding section see it (I think the same is true for personal clubs).
Yep. I sometimes forget to check my dinding and see a komen only after few days. If anda need to reach someone, anda can try Penulisan on dinding and also pm them
