That would be great! Would I be able to put your name down as a contributor towards Open Conference Systems on the following page: http://pkp.sfu.ca/ocs-languages/spanish
? Since we have a number of active Spanish contributors for both systems, I would recommend perhaps coordinating to divide work as may be appropriate. If you like, I don't mind sending an introductory email towards this end.
We will most likely be releasing stability releases of both OCS and OJS towards the middle or end of spring (these will not necessarily include major translation work as they build directly on current releases), and are very happy indeed to have such a pool of translators to draw upon.
