Since its launch, The Hub network has been used by 400 of the consortium’s members.
The Group said that all members would be given their own log-in details to access the site later this month.
Among its features; The Hub gives members the use of marketing materials; training programmes, webinars, an event diary and a staff directory.
It also enables members to download free personalised videos.
The Travel Network Group’s said its preferred supplier partners will also have access to areas of The Hub allowing them to interact with members and promote offers and incentives.
Si Morris-Green, group marketing director said the new platform would enable the consortium to engage with members and preferred suppliers “like never before”.
“[The Hub] completely underpins our goal of developing a community environment when we can all engage, communicate and grow," he said.
The platform has been designed and built by The Travel Network Group’s marketing and digital team.
Online manager Darren Holdsworth said: “The Hub is a new all-encompassing source of useful information for members that will build a three-way communication and engagement channel between ourselves, members and business partners, and has been developed as a direct response to what members have been asking for.
“Members ask us all the time for images they can use for their own marketing and social media activities, as they quite often don’t know how, or where, to source them from or the copyright laws.
"By giving them access to a huge free database of stock images, marketing copy, logos, it will save them both time and money."
