Hi
Some online 'meetings' use a simple "+1" to vote in favour of something.
Some people often use it in an informal way, as i do (i copied them).
Most of the ones i've seen (ie LibreOffice and TDF ones) have usually
talked through the issue until a mutually satisfactory proposal can be
posted or consensus reached. So i've never noticed anyone posting a "-1"
or whatever is normally used to vote against. I've seen people abstain but
that usually seems to be because they are busy and just didn't get around
to it (usually they had deputised someone to make their votes for them)
rather than out-right making a statement.
So it's 1 person = 1 vote = total support, although i kinda agree with
James' sentiment there.

Tom
