I have a problems- or maybe an idea. I have for example, 20 libraries on my host website- i mean 20 home branches libraries (Library A, B, C....). But i can change my OPAC site for only one interface. Is there some ways to change OPAC's interface associate with the user's information? Let me tell u more about this. In our country, it's expensive and impossible to have 1 hosting for 1 library (1 school), so we want to make a hosting for 20 libraries (20 schools) with one website like http://systemlibrary.edu.com. In this Koha library, we have 20 branches libraries with 20 staffs - not superlibrarian. Is there some ways, when patron A (branch library A) login in OPAC site, he can see messages, icon, schoolA's Logo... And when patron B (branch library B) login in the OPAC site, he saw absolutely other things (schoolB's logo, icon and messages...). Sorry for my bad english.
