I´ll be working this week on the plugins translation and I´ll give you the files when they are ready. I´m also planning to work on the Reading Tools translation afterwards; but this is big work and it would take more time.
Regarding the new version release, I´d be glad to help (if my amount of work here allows me to).
I have another question, but this is not closely related with the previous issues. However, maybe you have information about it or maybe you can ask to some of your colleagues at PKP.
A friend of mine tried to register in the forum a month ago, but the confirmation email was never sent to his account. Do you have any clue of what can be done? He tried to register twice, with different accounts and user name, and nothing.
