I'm currently trying to implement a function to check if a user already exists. I've read that this could be done by Rules whit the condition "Entity exists by property" but I can't find it anywhere. I've tried it with Rules 7.x-2.2 & Rules 7.x-2.3
Is this option still available or not? Or is it located in a other module?
it's related to this question: How can I check whether a username is in use?
