I can't answer

Hi,

I'm Davide, an italian shaper. I love this site but I don't understad how to reply in the forum...

for example I open a topic some days ago "...some help please..." and many people answer to me but I can't reply...

How can I do? I try to click " quick reply " button but happen nothing...

I'm sorry but I don't understand...

I can send Private Messages but not public message.

Thanks
