Where to network?

Like any new business owner, I'm keen to make as many contacts as I can.

Not only because I really enjoy meeting new people, but also because new contacts might become new customers.

Here are some of the sites where I network online. And they're all FREE to join.

• Enterprise Nation - a very friendly and active site for owners of home-based businesses.
• Flying StartUps
• LinkedIn

Does anyone have any more recommendations? I have a Facebook account but don't tend to use that for business.

Cheers

M
