I would like to use this site for family reunion participants to input their family birthdates, etc. along with upload photos to their family's album. Will this work with mutiple users at the same time?

If U try View>descendants . It will show descendants, pictures and year of birth: then print screen and save to a printable file..You can print it out in color... problem is it will take many screen prints.

OR try Reports> descendants> then right click to prints . Gives all in color photos also.

That's for reunions:.

If you want them to make the input>> then (IF YOU ARE SITE OWNER) see the new TP app they can upload and do it themselves.

Yes, the site is designed to work with multiple users updating the family tree at the same time.
