Last month, Facebook users were for the first time given the opportunity to reserve custom usernames in a move aimed at simplifying account URLs. Facebook had advised its users to approach the christening process very seriously as the usernames chosen by them would become inextricably tied to their profiles. 

Those of you who are still ruing your questionable choice of username can now stop.  Facebook has spread its arms wide open for all those still drenched in a cocktail of desolation and regret. In an act that manifests its magnanimity, Facebook is now giving users the opportunity to change their usernames, but they only have one final shot at getting it right.
