This is part of a series of Tech Tips aimed to assist Orchard users in adjusting to our migration from Invision Board 1.3 to Invision Board 2.0.
Here's some information which hopefully can help to clear up the difference between several similar-seeming features of the Orchard.
There are several very similar-seeming "Reply" buttons on a standard thread page, and the differences are very important.
First, there's the (Add Reply) button. This is pretty much the default way to create a new post and provides the greatest balance of features versus convenience. (Add Reply) takes you to an editing screen where you can use a number of features to create and format replies.
(Fast Reply) is a quicker, but less full-featured alternative. It opens a box at the bottom of the currently viewed page, where a reply can be directly typed, but lacks many of the advanced formatting options of the standard (Add Reply) screen.
A (Quote Reply) button (which looks like a cartoon head with a word balloon) should be located near each post in a thread, and this button takes you to the same editing screen as (Add Reply), with one difference. The post which the (Quote Reply) you've pressed is located nearest to will be pre-formatted as a quote in your reply.
Finally, there's (Add Multiquote). This icon looks like "+ QUOTE". When you press (Add Multiquote), it changes to (Multiquote Added) (which looks like "- QUOTE"). When in this second state, this means that the post this is located nearest is "queued" up to be included in your eventual reply. As many posts as you like can be queued up in this way. When you've selected all the posts you want to include, clicking the (Add Reply) button finishes the process. These "queued" posts show up, en masse, inside the editing interface as seperately attributed quotes.
