Eventor is specifically about membership, entries & results. At present Eventor does not expose details to users ie find a club and show me the contact details (unless you have administrative permission). This feature request is relevant if there was additional functionality added to Eventor ie be able to click on/hover over club names in event lists etc and then see facebook/web site details.
This is currently outside the current budget and would require more funds. It should be set up generically so any club can add multiple "services" ie twitter, facebook, flickr etc
this is also applicable to http://eventor.orienteering.asn.au/Forum/Thread/12 (facebook)
