By donating, you not only support the continued existence of this site, you also improve this site in various ways, by making it affordable for ForumBiodiversity to upgrade the server with better hardware and licensed non-free proprietary software, but also motivating the staff to work harder. ABF will always be free of charge (gratis) to use. However, if everyone donates a small monthly amount, it makes a tremendous difference for the forum's overall quality in the long haul.
