Using quotations is an effective means of replying to specific parts of another person's comments. It is also a very simple process.
If you wish to quote part of another's post, simply click on the "Quote" button at the top-right corner of the post. In your reply field you will see their post with [quote] at the beginning and [/quote] at the end of the text. Simply type your response before the [quote] and/or after the [/quote] and all will be well.
You can quote the entire post or a select part of it. You can also break it up into many smaller quotes to be more specific in your replies. You can do so by typing the [quote] and [/quote] designators around the smaller sections and typing between the quotes.
If you have improperly used the Quote function, your post may be edited by a moderator for the sake of clarity.
