Apple Logic Pro /LogicExpress Discussion

I'm a new Logic user - recently I weaned myself off of Studio Vision 
in an effort to get with the latest, greatest stuff.

In another Logic user group, I have asked twice in the last two weeks 
about how to give feedback to Apple about Logic features, etc. (I 
really liked the sub-sequences in Studio Vision, allowing a lot of 
flexibility in experimenting with song structure).

For some reason, there has been no response from the group.  If you 
go to the feedback area at Apple, www.apple.com/feedback - every 
product is there EXCEPT Logic.

Does anyone know a legitimate, practical way of giving feedback to 
Apple regading Logic?  Thanks.
