Problem with invitations.

Hi, everyone.
Thanks very much for the mails I've already got. (If you haven't sent yours yet, please include 'PRE FCE Saturdays' in the subject when you do.)
You may be wondering why you haven't recieved your invitations yet, and it's because Blogger has made a few changes to its page, so that instead of inviting you as usual through 'Settings', now I only have 'Permissions'. So far, so good, but the problem is that the only alternative Blogger offers in 'Permissions' is to remove myself from my own blog! Not exactly what I'm looking for.
Please be patient, and if you have any suggestions I'd be glad to hear them.
See you on Saturday.
Tom.
