we were quoting the last message in the thread
And that is the problem, which you have quoted yourself in rule 2.4:
2.4] Do NOT use excessive quoting. Only quote the message you are replying to and NEVER quote the message directly above yours unless you only quote a part of it. DO NOT MAKE PYRAMID QUOTES UNLESS IT IS NECESSARY. *
The last several posts in that thread are basically a conversation between 2 people only. It makes no sense that you are quoting the entire previous message. Just use "Post Reply". I'm sure everyone can figure out that you are responding to the last post.
Please let me know if further clarification is needed. Have a Happy New Year.
