I'm sorry for the delay in getting back to you!
Viewing new messages can be a problem and I agree. I think there needs to be a better way because when you click a message to view and respond, suddenly you are back to the front page of the forum and the software now thinks you have read all of the new messages since they were on that original list. You are right, if you click view new messages it is now clear of those new messages.
What I do is use the back button to go back to that list so I can see all of the new messages. Click it 2-3 times and you will see the list and then can follow the new threads.
CelticRadio.net Portal will solve this issue with a list of the last 15 messages on our frontpage. Hopefully we will have it up and running this weekend.
