At the moment wordpress is something I might plan on using to setup a blog for a local university project. There will be 50 students blogging for a two month period. I just noticed when I sent an invite to one that I could no longer send invites. Is there a reason for this, considering that one could send an invite via regular email and have the user sign up?
Also, more importantly, is there a user limit? Will I have issues adding 50 students able to post to the group blog?
