Hello, Due to limited time (it had to be done by tomorrow, when I go on holidays) I'm developing the first part of the program as a web application with PHP and Javascript (with which I'm more familiar), and that'll do the trick for now. Later on, I want to keep exploring Ruby and if possible migrate and expand this application. I'm very interested in Ruby and I am very happy with the response from other users like you in this forum. I just wanted to say that and thank you for your help so far. Hopefully I'll get to something when I come back from my holidays in a few days. So don't think that I asked and then disappeared ;) Cheers, and happy August. Manuel -- Posted via http://www.ruby-forum.com/.
