Pixton provides an embed code for Blogger (see the example below), or students can take a screenshot and add it to an MBC discussion.
Pixton works on a MacBook; they are developing an iPad version. Pixton for school has a 30 day free trial if you wish to set up classes for a project.
ToonDoo works great on a Macbook. The image can be "saved" to the computer and uploaded to MBC or can be embeded in a blog post (see the example below). You cannot create a ToonDoo on an iPad.
Bitstrips is app based, but at this point requires Facebook sign-in. They claim this will change soon. Bitstrips is free; the school version has a 30 day free trail and costs after that.
Toontastic cannot save work tot he camera roll unless you upgrade to a paid account.
