I understand that most of the guys reading this list are pretty busy.

I've been looking at one of the networking examples
( http://doc.trolltech.com/4.0/network-http.html ), and I'm adding some of its
ideas to my code. I thought that I should use a QBuffer because I don't want
to write the response to disk, I'd like to parse it with QXmlSimpleReader - is
there a better way to do this? Also, what should I use instead of QHttp?

Gmail hasn't corrupted anything I've sent so far, but I'll be careful.
