Hi Cosette, this is a good question and I have wondered if there's a way to track if people are using those functions?
Personally I use the Topic Indexes first if I'm looking for previous discussions on something (main forum and group) but if I can't see what I'm after I'll try the Search feature. As a Facilitator we have to sometimes edit the tags on members' posts so that they fall into a listed topic, or it may be the start of a new topic.
Was also wondering if there could be a Popular Topics feature which stood out and might prompt people to look at that first and then refer to the All Topics Index - does that make sense?
Cheers, Jane
PS: It was lovely to meet you and Annie at the training session this week :-)
