To two people in organisation A: I need to keep you two updated with the current development of the project I start with that organisation. From the meeting I had with senior management last month, they came up with so draft ideas. The project team had been work on more ideas thos am waiting for them to keep me in loop about that.
The organisation is currently working on a similar project with the Alzheimer's Society. You two just work for a local organisation and the way things are going with this national organisation, it might go beyond your geographical area! eg. just at that meeting last month I had a few people travel from London, Birmingham and Hull just to hear what I had to say.
To a group of people working a project: You lot have been very busy this project I started, I know cos my inside contact in your organisation emailed me. Now don't for get to keep me in the loop, you do have my email address go and add it the project mailing list.
