Hi there James,
I think you've just given me the answer I need!
I use 220.127.116.11 right now, so I see that there are tags in the HTML code. I also think I found the "citation_xxx" type fields. I was confused as I use Zotero (a freeware referencing software) and I couldn't get a good citation. But that's not a problem of the OJS but of Zotero.
So thank you for the info about the template! It'll certainly be useful in the future.
