sent warning

I sent out a reminder notice to guests expected at the CAO on the Labour Day weekend. Asked that they minimise their internet use. Told them that we were over-quota. Reminded them to plan ahead! To update their operating system or browser software, download planning lists (e.g. Skymaps.com), install software patches, update asteroid lists or satellite TLE data or star catalogs (for their astronomy software), and so on, before arriving at the observatory. Not that it will make any difference.
