Absolutely @stefaniej !
You are correct, right now there are only a few people who have shown interest in the other timezones, but keep in mind there have only been a few responses on the forum. That does not mean it will not change in the near future. A matter of fact, that is exactly what happened with the Concept group, and now there are two to help cover two different times.
To everyone who cannot make the current groups: Keep in mind we are only a week into this, so if the current schedule doesn't work, there are many more to come. Once it shows that there is a group of people in the same timezone interested in the same topic, another group will be made to cater to that group of people.
Needless to say this idea is still in its infancy, but as time goes by there will be something for everyone. Now is a great time to introduce other artists to the Community and/or Community Groups.
