Nothing really. I'm used to a small business environment and Calendar Club is very clear about everything and supports you well. I have seen the occasional criticism but its really from people that weren't suited to running their own business, took shortcuts, didn't do the work and then were somehow surprised that they didn't do as well as they had hoped.My point is that it's not for everyone but if you're ok to work hard for a couple of months you''ll do well. Is that a pro or con?
