Sorry to hear about the flu! That's not a fun way to bring in early summer, for sure.
Unfortunately, I'm new to BizNik, too (along with pretty much anything that has do with promoting a new online business....) My guess, though, would be that an open forum where people can post questions is probably a good bet.
For me, it would be useful to have two things -- WordPress tips and tricks to navigate the application, but it would also be very, very helpful to have ideas and thoughts about how to use a blog to promote your business. I've seen lots of un-helpful blogs out there -- but how to do it right?
Take care! And enjoy our beautiful day.
