Yep, the referral not being valid for users who used the promo code isn't really an issue for me. I was only interested in getting a really cheap host for a year, not in getting income from referrals.
I too have deleted my credit card details and disabled the automatic billing option
Finally, in response to Incog's comments, if I was looking for a serious hosting company, I'd undoubtedly go for i-web too. However, this is just a sandbox for me to mess about with till I get bored, or maybe somewhere to host my streaming radio. In any case, from what I've seen, they're a legit hosting company who have been around for a number of years... that's not to say that there aren't posts on the web complaining about 'em
And as good as i-web appear to be, even they can't compare with £5 for a year's hosting. But if I find this worthwhile, then I might be looking to them in Jan '06.
edit: bloomin' hell, lookin' at that link, Incog, they've got some great deals too. I think I will definitely be switching to them in Jan '06 after all!
