Safari Can’t Sent GMail Invites: Be warned Safari users. At this time Safari can’t sent GMail invites. At least for me anyways. I sent two and neither worked. So I used FireFox and the invites went out OK. However, it counted down my invites right, so I lost two. Oh well. Edit: It may be that the people I sent them to had free accounts, example Yahoo!, and their email provider may have blocked the emails from even entering. Not sure.
