Shmoo, thank you for your reply and I am sorry for not responding earlier – my screen still shows 0 replies to this post and the only reason I saw your post was because I came to write something sarcastic about the lack of help offered. I have come to this site a couple of times every day since posting.
Where I was stuck was on the ‘Pages’ part of the Buddypress settings page – I was under the impression I needed to create a page for each of Activity, Groups and Members sections at least, but had no idea what these pages did or needed to be functional. I have tonight again spent time watching videos trying to find an answer and found this short tutorial which showed that there are already existing default pages – that’s all I needed to know to at least get started.
Thank you for taking the time to answer – much appreciated.
