What we found that worked best was to 'follow' a thread, which you can do so at the top of the page in that thread. When someone answers, you'll get an email notification of a new comment and you'll have to scroll to the bottom of the page to see it, if it was added as 'add a comment'. As Cheryl mentions above, when you reply to a comment and there are several replies, you will need to click the 'view more' just below the original comment and it will expand that conversation.
Once you have all the threads you want to follow, on the main page of the forum, you can click 'Threads you follow' and it will display them all.
We understand that the forum could use some upgrades and we do take in the suggestions you give to pass on :) We've also shortened the monthly What's on Your Loom threads to help reduce how many pages each of those threads has.
When we hear of any upgrades from our hosting platform, we will let you know for sure. Thanks for understanding :)
