[HTML]But u realise that I m totally NEW to Linux..![/HTML]
Quiet frankly i dont think you could get away with that excuse cuz you seriously dont have to be a heavy linux user to learn how to do your own research. My advice is narrow down to what you want to do; for instance, do you want to deal with networking? If so then research about a networking project. Is it web applications? If so then phpmyadmin, apache and friends will be your core applications in developing your project. The projects you stated above are other people's creations to enable us create more projects. They are enablers. So unless you want to improve on their features then i dont think they will qualify as such. Personally am running a project on sms'es using Kannel and open source smsgateway and using mysql as my database. You get the drift??
Hope you get the picture now
