>> I've used BT Yahoo for years with only minor, infrequent problems. Never lost any data.
Sore point for me. I was one of those that lost stuff when they moved between BTinternet >> BTyahoo period.
Then at one point I used to get so much spam into it that when I forgot to check it for a month it had accumulated something like several thousand spam mails (something like 6-7,000 iirc) which blocked my mail. - This wasnt the spam folder but the main inbox.
In the end I had to phone up BT and get one of their agents to delete everything (including valid mail). :/
Must admit their spam filter is a heck of a lot better these days though
Ive also used hotmail for years - but many a time Ive lost mails etc because Ive forgotten to log in once a month.
So I suppose the moral is that who-ever you use their will always be pros and cons.
