the future of libraries in the digital age
I strongly recommend you join the Koha Mailling list and post your specific questions there. People in the Koha community are very helpful but you do have to be specific about what your questions are.
To join the mailing list, go here: http://lists.katipo.co.nz/mailman/listinfo/koha
And you may want to check the Koha documentation to get started. It's here: http://koha-community.org/documentation/
