The WordPress for Toastmasters project allows a Toastmasters club to take advantage of everything the WordPress blogging community has created for an easy-to-use yet powerful platform for marketing and social networking, along with Toastmasters-specific functions like managing meeting agendas and member role signups.
This is offered both as open source software (RSVPMaker for Toastmasters) and as a free service for Toastmasters clubs (subdomain websites running the same software). This video dramatizes the idea of integrating the functional aspects of a club website (like inviting members to sign up for meeting roles) with the web and social media marketing required to keep attract new members.
