If you have children, invest in their future online presence.
Secure their Twitter, Facebook, Instagram, Domain etc.
They will thank you for it later on in life when they have a decent username rather than something like Deveci_310855
I would recommend starting with an email address first. Google Mail is a good start as this will also give them access to YouTube and so much more of Google’s products.
Once you have registered a friendly email address, go on to secure their social profile names by linking it to the new email address you have just created for them.
