WordPress invite expiration

What happens afters 7 days when an invited person doesn’t accept the invitation? Can I do another invite?

WordPress and TinyMCE

Wow, I am just testing out the TinyMCE / WordPress editor and I am really liking it. This makes live so much easier for the average blogger. Using Firefox I couldn’t find a single bug in the WYSIWYG editor while last time I checked TinyMCE was very buggy. So either the TinyMCE crew or the WordPress made a lot of progression..

Oh, and when are whe going to be able to host images @ wordpress.com?

Update 

Strange I did not notice it before: I can upload up to 25 mb. Way to go WordPress!
