I 'm very happy to announce that there is a translation of the developer HOWTO for blocks in Spanish available! This is a totally up-to-date version of /blocks/HOWTO.html, reflecting the current state of the Blocks library. Personally I hope that it will continue to reflect the current state of that library for a long time to come!
All the hard work for this translation (including several revisions to keep pace with the original) was volunteered by Astrid Sanchez of solearning.com. Lots of thanks from all of us, Astrid!
For the moment, you can download the translation from this forum post (I 've attached it). I hope we can find a more appropriate place for it soon.
Thanks for the translation. A friend of ours is currently using the document.
