[Tails-project] Reminder about sponsorship to attend events …

This is an automatic reminder.

In general, you should not have to spend your own money to attend
relevant events, such as conferences, on behalf of Tails: in most cases
the project will reimburse the corresponding expenses.

See our documentation about how to get such a sponsorship:
