A restricted blog for a traveller

I have an idea.

If you are travelling overseas for a short term assignment, you can create a blog and restrict its access to a few identified family members and friends.

You can update your blog at regular intervals. This is to tell them that things are all right.

You can store your contact information, eg address, telephone numbers, so that the family members can get in touch with you in an emergency.

You can also share your experience, eg photos, places of visit, etc.
