Recently I have had some issuses with people that want to host a show(even set a date) and then not follow through. Last month 4 out of my 5 hosts cancelled or just wouldn't return my calls. Now this month I have yet another host that just will not return calls or e-mails. I am looking for ideas on how everyone else deals with this. Also when should I draw the line and not contact them anymore. I don't want to be that host that just will not leave someone alone!
