Many of the posts in this forum quote other posts. Here is a tip that makes it easier to follow the flow of discussion: Instead of using copy/paste, there is a neat little quoting feature you can use. Simply click the "quote" button in the post you want to reference (it is located next to "edit"). It will automatically place the post in a new "reply" box, it will mark the quoted post with lines, make it bold, and cite the original author. If you don't want to quote the entire post you can simply delete the non-relevant text. This makes it much easier to read and to follow the flow of the conversation and tell what is the quote and what is the reply.
OR, you can use the codes {quote}to separate a quote{/quote}, {B} for bold text{/B},{I} for italicized text{/I}, etc. (You have to use brackets [ and ], NOT { and }, I had to use { and } for this demonstration so you could see the actual code)
