what annoys me is that I have to log in to read mumsnet because I CANNOT read active conversations with all those bloody for sale threads everywhere and I can't seem to get rid of those unless I log in.
AND even when I did log in, it didn't save what I'd done before so I had to go through the whole rigmarole of excluding what I didn't want all over again.
Took me a couple of minutes before I could start reading which annoys me immensely (and will annoy me even more if I'm trying to do this while I'm busy!).
