I was really tired of worrying about my schedule and everyone else's. We are a writer co-op with almost 100 people working mostly from home. Appointment details were getting dropped, teleconferences missed- the eStudio calendar fixed all that. eStudio combines our Personal, Group and Supervisor Calendar all in one.
Now all our individual appointments and meetings are organized online. We can easily see when people are available. Since eStudio includes project management software, knowing where a work group stands on project task is also a no-brainer. The automated email notification and reminders system makes sure that everyone is on the same page.
We did an extensive web search and free trial exploration of various calendar technologies. We looked at a lot of options...and tried one of the biggest names out there, but switched to eStudio because I have real control over what each person could do in eStudio. It's as good as anything I've tried on the web, maybe better.
