Can I send more than 10 messages within 24 hours?

WWOOFers are allowed to send 10 messages a day, not more.

That is because hosts receive many requests, thus it is important to send complete and personalised questions to each of them.

If WWOOFers don't do it, hosts' inbox would be full of identical and impersonalised messages. This limit helps to choose between hosts, and assure them that the sender is going to reply afterward.
