I don't know if this is planned for 2.1, but one thing my members found irritating was the necessity to check the:

"Add a copy of this message to my sent items folder" box every time they sent a message if they wanted to save it. In the old versions of IPB, you could set it to be automatically checked.

Could you either restore this functionality, or have a function in the ACP which makes it so that sent messages are always saved in the Sent Items folder?

Thanks :)

You can achieve this by editing the templates although I do wish it was a default option :)

Also:

When you send a message via the Warning Levels feature, can you have the option to save that message in your Sent Items folder?

+1 to both

Sorry if this is offtopic, but what does "+1 to both" mean? :)

It means agreeing to both points made :)

Ok, thanks :)

These are easy suggestions, I hope they can be implemented in the next version of IPB.
