Have you ever needed to setup a conference call without access to a corporate conference calling number?
This summer I had just such a need. For four months I used freeconference.com for weekly morning conference calls. Instead of scheduling a meeting every week I used their reservationless conference feature to have a conference call always ready to go! This enabled the meeting notices to have the same dial in number and access code and alleviated me from having to manage the meetings through their software. No need to hand out codes to attendees each week.
This software has worked so well I hadn't logged in since I set it up. Fortunately my password manager saved my password so when I accessed the site today I didn't have to dig around for my credentials.
