Hey, 

Here's my use-case : 

I want Salesforce to automatically fire an email when a field is changed in the User Object. 
So I'm using an Apex Trigger to do that. 

The only problem is that I want the email to be sent 24 hours after the field has changed and I'm struggling to find a way to do so...

Is there a way to delay an action called by an apex trigger ? 

Thanks !

Unfortunately, Community Cloud doesn't offer instant messaging and that's something we're looking to implement in our social network.
To sum up we're looking for a "Messenger" to add to our Facebook-like.
At the moment, we thought about integrating an external solution. We would develop a instant messaging tool that would communicate with Salesforce community cloud.
Any ideas or advices on how to advance on this ? Is integrating an external solution the best option ?
Thanks guys !
