Before you start blogging there are a couple of things you need to do:
(1) Have a Google Account https://support.google.com/accounts/answer/27441?hl=en
(2) Preferably have the Chrome browser installed on your computer or laptop. Or your Android or Apple tablet or phone. You can use another browser, but in my opinion Chrome works best with Blogger.
You should also think of a name for your blog.
Which family stories do you want to share - current events and photos, your own story, or information about your ancestors? The choice is yours. Once you start, the blog may take on a life of it's own and change. That's OK! You may discover that you can help other people by sharing your knowledge. That's even better. And you just might make a connection that knocks down your brickwall and that will be absolutely grand!
All you have to do is start.
To help you do that, here are the slides from the workshop.
