I too cannot read some messages, as the poster isn't sending in plain text.
Only when the post is later quoted by someone else does it become readable.
PLEASE help out us computer dunces in the crowd by posting in plain text.

 Hi all,
 I noticed that the digest emails and
 the archived emails online have some
 entries and replies that are pretty
 much gibberish. I use Outlook to receive
 emails. Any idea why this is happening
 and how to fix it?
 Thanks.
 Kevin
