[ic] updating our site

[Dave]

Hi there, we have a toy store using interchange at the moment. So far  
it has a browse by category section, but i want to have a menu on the  
left hand side with browse by category (with a drop down menu of the  
categories), browse by age (with a drop down menu) and a browse by  
brand(drop down etc). if i have the system all workijg at the moment,  
but want to add extra search or category types, is it a long and  
drawn out process? or can these changes be made simply? that is my  
first question.
regards
Dave Stringer.
