I post this just to close the story.
Finally, i'll go with ASP.NET, and the IBuySpy Portal thing. At least it's not raw ASP from scratch (and no, it wasn't obvious for everyone).
So, there's yet another thing to learn... Is this going to stop someday? 😊 At least, i'll be able to use what i know of Visual Basic (eeech, didn't THAT sound weird?)
Thanks again,
Jorge
