Please note that you can only create a group if you are a supporter, so as a newbie, you are prohibited from doing so.
I think this is a good rule because it prohibits newbies, unfortunately, from starting a flood of groups which they are not dedicated too that will do nothing more than flood the system with groups that have no supporters. Now, this is not to say that every newbie would do this because there are alot of wonderful newbies, including myself.

When a supporter starts a group, you can be assured that he/she will, in fact, stick around and is wise enough to realize that the group he/she started serves a relevant purpose which will benefit the wonderful Basenotes.
