jcomments

it looks like jcooments 3.05 has the plugin for sermon speaker in it, does it work with sermon speaker 5.x? Can it work with a series detail page? or should one replace their plugin for the one on your site? we would like to have commnetting on the seiries and not individual sermon pages since all sermons are under one series

You need the plugin from this site. The one shipped with JComments seems to query SermonSpeaker database fields which are no longer valid.
If you want you can send them my plugin so they can include it.

The comments only work with the single sermon view and only the extnewline, allinrow and icon layout does support it.
In other layouts you will have to add the needed HTML for it in an own layout (see www.sermonspeaker.net/documentation/layouting.html and www.sermonspeaker.net/documentation/layouting.html ).
