Not to take anything away from the deep dive in the recent messages about servers, I would like to stress the simple use case for many: just logging and sending notifications without using any servers.
With the addition of BLL in the Simple Log cards, its use for logging is efficient and obvious.
PS
@Arie_J_Godschalk I will submit a feature request for an AND card with a list of severities. That would be more efficient than text based Logic AND cards (“…is exactly”).
