InfoPath Dev

I have a question about forms that will be put into SharePoint. Do all other people that need to edit form need to have the InfoPath program.

If you have MOSS, you can make your form editable by Internet Explorer with Form server, otherwise, you need Infopath client to open your form.

I think there are other considerations too - if you are using repeating tables and some other controls, Sharepoint requires the client to be Infopath rather than IE. I've run into this issue as well.

  Repeating tables is support on form server, you can have some trouble to publish them to SharePoint but it's supported.
