Now when there is already some content, it's time to announce planet phpMyAdmin. You will find there posts from phpMyAdmin contributors including Google Summer of Code students, so you might find there what interesting ideas they have. Please note that this blog does not have to contain only phpMyAdmin related posts, it's just for all what contributors do (as usual on other planets).
It currently lives on http://pmaplanet.cihar.com/.
PS: If you think your blog is missing there, please drop me a note.
