As Miekal and Lon have noted in different ways, attachments should
not be uploaded to the list. I found the info about grafting to be
interesting, and I think it was sent with the best of intentions.
However, that is beside the point, as the guidelines for this list
states no attachments.
Many people still have (slower) dial-up connections, which means
large attachments can take 10+ minutes to download. Secondly, as
virus-writers become ever more devious, opening a large attachment is
fraught with danger, even if it appears to come from someone you
know.
Miekal has offered a solution that would appear to offer a solution.
Perhaps he can give more specific instructions on how to upload to
the permaculture wiki. In the future people can post the LINK to the
item in question, saving bandwidth and making people feel more
secure.
