PODTUBE is a personal project and was originally developed to be used only by its creator, but then the creator decided to open it, making PODTUBE available to everybody with similar needs, for free.

However, PODTUBE has server, bandwidth, development, maintenance and improvement costs.

And the number of users is growing daily, requiring frequent service upgrades to keep a minimum usability level.

Its continuity as a free service depends on your support.
