I am Felipe Lema and I am a computer engineer student from Chile. I am currently using Tcl/Tk as part of my internship "somewhere". If you want to contact me just send an email to [concat [string tolower $first_name] "." [string tolower $last_name] "@" gmail.com] and try to write it in spanish, as not to get filtered as spam.
I don't have a web page or blog as I like to have physical contact with all the people I know, though I have posted some things (not all about Tcl) in the net.
