Right now, when you choose the setting for Forum > Options > Emaill >Email Address Settings, there's an important note hidden in the Help icon:

Note: These settings, once made, are global in that they will be used by WordPress for non-forum emails as well.

Well, that kind of defeats the purpose of having a seperate Forum email address!

I don't want my Forum from email address, and my Admin from email address, to be the same – I want them to be different!

Please consider chaning this on future versions.

Thanks,
Sean G.
