Nothing ventured, nothing gained

I want to ask the English tutors (and all tutors) to provide more group conversations so it would be possible to sign up at the last minute. It is difficult for me to sign up in advance, that’s why I would appreciate being able to do so. This was suggested a month ago or so however, there still are many 1 on 1 conversations, but very few group conversations. It would only be necessary to make time available . There is no need to elaborate on the topic of the conversation. I’m sure there would be a lot more participation.

My time slots are : before 7:30 and after 20:30 (GMT-0400) US/Eastern) and I’m an advanced learner.
