Does not support February 29

This does not meet my needs. I need a daily tip for every day of the year, but this plugin will not allow an entry for Feb. 29.

Also, I deactivated and deleted the plugin, but doing so did not remove its table from my MySQL database. I had to do that manually.

Sorry. Otherwise, it looks pretty good. I did not fully test it though, as this limitation was a show-stopper for me.
