@aran , I have sent you an email with the link to the guide.
Everyone else (especially those who I gave the link to previously), I had a bit of a tidy up in my Dropbox account a while ago, and without realising that this practice would render the link to the file useless, this is exactly what had happened!
I have sourced the new link and forwarded it to Aran so that the guide can be made available to everyone from the SSi website.
Challenges 24 and 25 still need to be included mind, and will be once they become available. Although realistically, I could get them from the northern course and include the “Southernisms” myself, I do want the vocabulary made available to everyone to be as accurate as possible.
I apologise to those who tried to use the link recently, only to find it no longer worked, and hope the new freely available link will be of great use to everyone!
