One of my recent projects has been to run YetAnotherForum (YAF) inside a Sitecore website (read this earlier post). The changed YAF source can be found as an open source project at http://trac.sitecore.net/YAFIntegration.
Now the project has been expanded with a Sitecore package that allows you to control the behaviour of the YAF control from inside Sitecore. The optional package consists of a custom field and a sublayout that allows you to set which board, group or forum that YAF should display.
When placing the custom field on a page, it becomes possible to select which board, group or forum that the sublayout must display:
The sublayout uses this data to display whatever is chosen:
The function gives you the possibility to display one forum on one Sitecore page, and another forum on another page. Or displaying all forums on one page, one group on another page, and one forum on a third page. And so on and so on.
The feature is part of the optional Sitecore package included in the YAFIntegration project. Read more about the package here: http://trac.sitecore.net/YAFIntegration/wiki/Optional_Package
