Hi Bruno, Michael and Karen,
Thank you all!! Glad you like it!
First of all I must tell you that the PKP Forum was, and is, really useful to me.
Briefly, I mostly added or changed code in the .tpl files of the "templates" folder, so no were plugins added. Other files were also modified, as in:
lib > pkp > templates;
plugins > blocks
& locales .xml
During the process, 206 files were changed, 2405 lines of custom CSS were added for each style, a few JS to spice up, a little help from third-party codes, and 112 coffees and 1,823,134 billion beers drunk. No pandas were harmed.
As for github, we're thinking about it. It would be really nice if someone finds something useful, even if I may be ashamed of some really really nasty hard code.
Besides I've been playing with OJS 3.0 for a few months (also a new website design, this one is from 2013) and we may upgrade at the end of this year, so I may share before both versions via github. I'll let you know anyway.
Finally, dudes, the work you do at PKP... Chapeau!
