First of all, note that what you are calling a "forum" is actually a
newsgroup. You happen to be participating in this newsgroup by using the
web interface, which as far as I'm cocerned is the slowest, clunkiest,
most error-prone method there is. You might want to do yourself a favor
and switch to a newsreader, such as Outlook Express, which comes with
Windows. See

Regarding personal replies, most of us feel that replies should be sent to
the entire group so everyone can benefit from them. However, if you use a
newsreader instead of the web interface, you will see that a personal
reply *is* possible, as long as you have a valid E-mail address for the
person you want to reply to. Many of us (me, for example) don't post
using our real E-mail addresses because we prefer not to get personal
E-mail from newsgroup participants.
