A number of companies now provide white label social networking platforms that enable other websites to build out their own communities.
These services can be either hosted or based on your own server and can be used by blogs and other websites to create a community around the content and brand.
We take a look at ten of these services:
Flux - Backed by Viacom, users can either create a new social network or add a network onto an existing site, while content such as video can be distributed to other sites.
Flux has the benefit of Viacom's money and brands, but has been criticised by NIng for limited control and customisation options that users have over their Flux networks.
KickApps - This is targeted more towards web developers, KickApps enables companies to add social network features to existing sites.
It requires more technical expertise than NIng to set up but it does offer more customisation options.
PeopleAggregator - With a range of free and paid pricing options, PeopleAggregator will host stand alone networks or add social media features to exisiting websites.
GoingOn - Providing social network features to exisiting websites as well as hostinf networks, GoingOn offers similar features to PeopleAggregator and is more understandable to the normal user.
vibEngine - With no free options, vibEngine offers specifically tailored social networks.
Kwiqq - providing a social network platform for brands, Kwiqq has created networks for clients including First Choice.
Ning - The largest of the white label social network providers, Ning now has more than 80,000 social networks created by its users, and is easy to use.
Free to use, Ning offers an excellent range of customisable themes and gives users complete control of content and branding. It's backed by Netscape co-founder Marc Andreessen and has bagged about $44m in VC money.
SnappVille - Offering its services free, in return for a 50% share of AdSense revenues, Snapville provides custom social networks for a range of business sizes.
CollectiveX - This allows users to create 'groupsites' which can be public or private, and used for business or social reasons. CollectiveX is mostly used for professional purposes.
CrowdVine - This is one of the simplest services to use, though the features are more basic, and CrowdVine offers less customisation than some of its rivals.
