I think the problem is caused by the MathGroup mail server. It seems
that when you send a post to the MathGroup with an equality sign the
same post is sent to other MathGroup users with the equality sign
doubled. In other words = is replaced by ==. This is very
inconvenient because it means that a lot of code when pasted into
Mathematica will turn into nonsense. The problem is clearly on the
server side and I don't think that we can do anything about it. I don't
know how long it has existed as I have not been very active in the
MathGroup recently and I only noticed it because of your post.
[I have checked the raw emails that came into my mailbox and I
saw ======== in the mail instead of ===. My server is not
doing anything to the posts as far as I can see. Note that
the posts come with "=" as hex 3D and other hex codes instead
of ASCII. This may be the problem with some server before
it gets to me - Moderator]
