I would have thought you could use any web-based email account (hotmail, yahoo etc) on tiscali broadband. go to the relevant site (msn, yahoo) and create an acccount.
tiscali provides your net connection, it doesnt limit sites you visit
Unless you have paid for a "premium subscription" you can't download hotmail web-based mail. You will have to go onto the internet using Internet Explorer or another browser (Firefox is much better - and free) and just go to the hotmail website.
If you want to use POP / SMTP settings on your tiscali mail programme then get yourself a 'yahoo.co.uk' e-mail address. This allows you to download webmail freely in a mail based programme on your computer.
