Hi Laurie, welcome!
We are brand new users of Koha Express.
For anyone who isn't aware, "Koha Express" is the name of a service LibLime is offering, using "the most current Koha Project release." You're in luck Laurie, because 3.2 is just around the corner and it's got lots of bug-fixes and enhancements.
there are some things (MARCedit) I haven't tried yet.
I don't know if you saw it, someone posted a link the other day about a new mailing list that might be useful if you're getting into MARCedit: "You can subscribe to MARCEDIT-L at https://listserv.gmu.edu/cgi-bin/wa?SUBED1=marcedit-l&A=1" I notice that one of the enhancements LibLime offers for Koha Express customers is OPAC Customization. I write about OPAC customization on my Koha Blog here: http://www.myacpl.org/koha. If you've got some HTML and CSS skills you can do a lot on your own! -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
