Hi Owen, and thanks for your rreply.
Well... I experienced some problems when I wanted to add some user categories in Koha's admin interface. I had to modify the templates to be able to use the feature -- I'm using lynx.
It would be invaluable to our efforts if you could file bug reports for problems like this.
Actually, we examined the issue on #koha-fr when it appeared, and I think the reason why I didn't file a bug report was that neither I nor others on #koha-fr knew how this kind of issues could be fixed. One of the difficulties was that the javascript does a few verifications and transformations that are not performed at the server-side. For instance, if I remember correctly the category codes are upper-cased in the javascript, and this is not double-checked in Perl. And: I certainly agree that modyfing the official sources is better than doing personal modifications. Sébastien.
