In the past folks have had to wait way too long for the comments page to load because we had so many comments on some pages – i.e. Sandbox and Reader Alerts.
Finally I figured out how to make this change and now I have it set up to load a limited number of comments on page 1. If one wants to see older comments you will have to click ‘older comments’. I currently have it set for 50 per page (versus over 1000 before)–but I can tweak to 75 or 100 if that looks advantageous. The key is to get the page loaded quickly so you don’t have to wait–but yet maintaining the history of comments.
