As a very longstanding subscriber, I have some comments and suggestions.
First of all, I am disappointed at the lack of communication regarding the departure of Fiona et al and its consequences.
I only found out what was happening by accident when I had a look at this forum.
As paid subscribers, we should be getting new lessons on a regular basis. The very least one can expect is an explanation and an apology, plus an offer of an extended subscription to make up for the lost lessons.
Regarding the lessons, I had been less happy with them over the last several months, and found myself studying them less and less. The upper intermediate lessons were becoming too difficult and were not focused on language that is usable in everyday conversation.
I suggest the following: formulate lessons around everyday situations. Avoid highly complex structures and vocabulary that is not used day to day. Try to have the lessons follow one from another, so that some vocabulary is used over and over in different situations and possibly in somewhat more complex ways, as the lessons progress… Use more words from the lessons in the review section. Use shorter sentences in the review lessons.
May I add that it is distracting when the hosts are too chatty and overly personal … with excessive laughing or giggling! I did appreciate the hosts who have left but this was sometimes an issue with them.
