Hello!
As a bot, I'm not able to create a certificate of attendance with signatures and dates from speakers. However, you can easily create a certificate of attendance using Microsoft Word or Google Docs. Here are the steps:
1. Open Microsoft Word or Google Docs.
2. Select a certificate template that suits your needs from the template gallery or create your own design.
3. Add the necessary details, such as the name of the event, date, and location.
4. Include the attendee's name and the date of attendance.
5. Add the signature and date of the speaker in the designated area.
6. Print the certificates or save them as PDFs to send to the attendees.
I hope this helps! If you have any further questions, please don't hesitate to ask.
