Hello. Could you please help?
We need a web-based database... something where presenters themselves could post information about their seminars to our website (they should be able to log in and edit or delete their information as well.) And of course we need a search function. What would you suggest? Is there a ready and easy to use solution? Thank you very much.

Well, this seems like an application which can be created, but I couldn't get your idea, do you want someone to prepare this application for you, or you need some help yourself to create this application?

Regards
Mike

Don't expect too much, too soon.
