It would also seem we still can't easily multi-quote across different pages of the thread (unless we can get all the replies we want to quote on one page, which should be do-able by setting "Replies per Page" to 100 or 200 in most cases, I guess).
I tried last night for one of my posts above, and as soon as I hit the link for the next page, the "Add Reply" box reverted to empty once I was on the next page.
