Help wanted:
If you like the basic concept and want to contribute ideas to sapotora feel free to contact me.
I want to discard the current default skin and create a new one, that it lighter and compatible with IE. Making a skin in Sapotora is pretty tricky, so please contact me.
If you need other methods of receiving and sending mail, please contact me. Creating plugins in Sapotora is very easy, but it is not documentated yet.
