Microsoft has unveiled a free HD Skype tool for small business users called Skype Meetings. It runs on a browser and will let you meet with up to 10 people for the first 60 days, and a maximum of three after that. Users can also share screens and PowerPoint presentations, and the organizer can wield a virtual “laser pointer” or mute users. Such features are already available with Skype Business, but that app requires a paid Office 365 subscription. With Skype Meetings, however, anyone with a link can join a chat.
