I am really gald to have a quick reply from you, thank you in advance.
let me be very frank with you, I just heard of it in the appfuse forum and
started searching about the family tree web app, I am going to build a web
application for my final year project in university(I am in Malysia), then
somebody suggested this web app, and i got interested, the first search i
faced in google was you and your application, thats why i sent you a post in
nabble...
actually i wanted to build this app based on java, I am not that much
familiar and professional in frameworks, do you think i can do the job ?
what should i do for the first step ? do you need more info ?
