I just love this question and I have read many good answers,adding mine lol.
Firstly I have a great sponsor, always helping me, thank you! My co-sponsor on the other hand, well I got another one!
I agree with what someone answered, if your sponsor is non-responsive, they are not serious about their SFI business, get a new sponsor! A sponsor without a team, not helping and guiding them, is not a sponsor!!!
