Historically you've been able to add comments about any contact in your Glasnost. What you've not been able to do though is email them directly from within Glasnost. So you would have to go to your email software and send a message from there. If it was something you wished to make note of in Glasnost you would need to copy/paste the message over. But now you can do that from within Glasnost.
Next time you want to send a contact an email use the usual comment pop up. You will see two new additions to this form. An option to send an email and add a document. As below:
Then if you want to add a document the form changes to this:
Now if you submit this form the information will be stored in Glasnost (including a link to the document you attached) but also sent as a neatly formatted email to the contact in question.
So your contact receives a nice email, and you have a permanent record, in the place you need it most, of the correspondence.
And if your contact replies to the email you will receive this message and it will be automatically added into Glasnost.
Hopefully this will help you keep everything you need together whilst still allowing you to contact people by email.
