Since we migrated to the new system, the way we can reply to topics has changed slightly. This seems to have caused some confusion and is causing the A&M team a bit of a headache trying to enforce the CoC.
In the topic view, you will notice that there are two different types of 'Reply' button.
The first can be found in the footer of every post. This is actually a 'Quote' button and will create a new post with a block of quoted text. This is not necessary unless you wish to directly quote another user's post and should not be used to post a general reply to the topic. Too many quotes in a thread make it difficult to read and looks a bit untidy.
The majority of replies should be made through the 'Quick Reply' box at the bottom of the thread since this will not quote text. Here you can also find the 'Full Editor' if you wish to add images, links, tables or bullet points to your post.
Update for Tapatalk App users.
The Red arrow shows the "quote" button. To be used when you wish to add a limp of quoted text to your post. Not strictly necessary when replying to the previous post but handy if you want to respond to a specific post further up the thread.
The green arrow shows the general reply button. This is the one that should be used in most circumstances and posts a reply without quoting a previous post.
