I'd like to have some fields on a page where a user can input some information and then that info will be visible for any other user that visits the page. Other users could then add or change the fields as well.

Not sure if this is in the range of WDB/RSD. If there are any other plugins or scripts that might help just let me know.

See picture for example

Hi Jeff,
For that I think I would just use RSD or the html editor to build the proper scripts.

Thanks Eric.

Can you give me a suggestion of what to be searching for? I'm not really sure what to start searching regarding any type of scripts?

You will want to build a form and submit it to a database. Then you echo back the results with a mysql select.
There's a few ways to go about this. Two forms or one form. With two forms you would use one to insert the data and the other to update it. With one form you would dynamically add more inputs when a user clicks a button to add another line. This method is a lot more time consuming. If you go with the two form method you could use a form made with the Form Builder to submit. The second would be a custom one but not hard to do. Let me know as I can guide you with the scripts.
