Small Business online groups

Hoping a few other small business owners on here might be able to help out.

We're now full time in our own business (woo hoo! :D ), loving it, but also struggling a bit with the networking (and social!) side of things. I would join up with a real life business group/networking group, except that we're on the road so much and across so much geographic area it's not really practicable. (Also when we're not on the road we're currently in Narooma on the south coast of NSW - very small population).

Can anyone recommend some online based groups? Or ones that have a main meeting point and meetings in several areas? (ie like we have on here with meetings just about anywhere in Australia)
