Virgin Media Comment Boards

Virgin Media's portal receives over 150m PIs a month. They wanted to increase this by encouraging users to engage with their great editorial content. Their idea ......
"We want to have a super simple commenting system that allows site visitors to post thoughts on any piece of editorial."
Jelerang set about scoping a tool that was easy for site visitors, easy for editors and easy for moderators to use. All the way working closely with the key members of the Virgin Media editorial team. The system was delivered in stages ensuring quick time to market and generating an additional 10m PIs a month.

Needless to say Virgin Media were very happy!
