In fact the difference between something like
=SUM(A1:A3) and =A1+A2+A3
where SUM ignores text entries can be readily seen in
A1: 1
A2: ="" or a single space or anything else that is TEXT
A3: 4
A4: =SUM(A1:A3) or =SUM(A1:OFFSET(A4,-1,0)
if you use
A4: =A1+A2 +A3
you will get an error #VALUE!

Use of a real name and a hotmail address -- that you look at for
newsgroup use would probably work a lot better for you. At the
very least it would be a lot more friendly when asking others for
help. You can set the hotmail spam filter very high but not to exclusive
email names only. Hotmail does have very good spam filtration
when set to "Enhanced -- most junk emaikl is caught" -- you set
your options from the options link next to the Help link in Hotmail.
