It's a fair point if you're quoting a complete post just to answer a few words in that post. Some may not know that you can delete the unwanted portion of the quoted material.
On the main issue, I'm always happy to be the resident wet blanket. There's no silver lining that I can't match with a cloud but I'll try to do it constructively.
if someone could explain how to delete the unwanted portion
It looks like the delete function isn't enabled so your best bet is to edit, maybe with a message requesting a moderator to delete.
When you do Reply With Quote you get the original post between the square bracket post delimiters. All you need to do is use 'Delete' or 'Backspace' keys to **** the unwanted words.
A thread may also exist but it would be helpful if there was a thread for general horse racing questions around terminology, practices and techniques for the likes of me who are still learning the lingo and find it tricky to find the information on line. There is still a lot of terminology I’m confused by and techniques used in horse racing when analysing a horses performance or race. It would be helpful if and when you have time to answer such questions.. You can’t understand something you’ve never learnt and it would certainly improve my knowledge and understanding of the sport.
