This is a feature we used on Deputy a lot, the ability to write notes on peoples shifts like, Sarah is keen to work if you are looking for someone, big push in abc venue at 7.30, please do xyz for prep for tomorrow. Or when there is a vacant shift happy with different hours say the shift is 11-5 and you can write happy with someone working 12-4 claim and let me know. I so see this is noted below and a link to an article but the article no longer is live and I can't find how to do it anywhere. The feature of comments doesn't have the same effect. Thanks
