Not a "Reply" Option for Every Post....
When someone replies to my comment on a thread, and I want to post a reply in response, I find no "Reply" option at the bottom of their post. How do I reply to their reply?
There is a limitation of 5 sub-levels for any thread branch, when the last reply posting has reached that theshold, the Reply link is no longer available for that branch.
As a work-around you can add your reply to the first post (the topic starter) in a thread, that will start another branch, however, you may want to indicate in your posting which reply below that you are responding to.
Especially without a quote function, I do think the sub-level limitations will be a major problem (especially, obviously, on long threads).
