Hello Rahul, >From a technical point of view this is a very interesting proposal. Thanks for challenging a task which may bring Harmony more interest and customers.
BTW, I noticed that you mentioned getting feedback, testing, publishing and implementing in your proposal. I would rather call these items "process oriented" than "deliverable oriented". For me it would be more interesting to hear that something works on Jikes + Harmony, or even to know where to download a bundle capable of launching "Hello, World". Also defining deliverables allows your mentors to check if the project is successful. Thanks. On Sun, Apr 6, 2008 at 2:00 PM, <[EMAIL PROTECTED]> wrote: > Hi Developers, > > My name is Rahul Mehta.
