Ask HN: Is anyone using busycal and busycontacts as CRM and calendar?

I&#x27;m looking for a lightweight team collaboration platform. I am using 2do for my personal todo lists and task gathering. Which is sadly, not useful in a team context.<p>I like the one time fee on busycal, the CRM addon is hopefully well working and therefore very nice to have.<p>http:&#x2F;&#x2F;busycal.com&#x2F;
