I am administrating a blog for a class I teach of thirty 8-9 year-olds. I have used a 2nd email (i.e. not the blog email) to set up a contributor account. I want the children all to be able to use this account to contribute to the blog. The trouble is when several of them login at the same time and they try to save their post the site gets stuck (just saying that it's saving). They are using Firefox. Is there a solution to this or is there another way of setting up multiple contributors without them having to have emails?
The blog I need help with is damersred4.wordpress.com.
