Publishing remotely

Greetings;

I have several questions about remote publishing.

1) Will the Mac app MarsEdit still work with EasyBlog 5.x?

2) Has anyone tried the iOS app BlogPress with EasyBlog?

3) If using either of the above apps with EasyBlog 5.x, can the default editor be set to Composer Blocks or does Legacy Editing need to be selected in the Settings?

4) Will email publishing still work properly if the default EasyBlog editor is Composer Blocks?

5) Sorry if this is a stupid question --- can a user log directly into EasyBlog to to create a blog post?

Thanks
