In an effort to combat forum spam, disposable emails from several providers have been post-banned.
Whilst I'm at it, being hosted in the UK we're legally duty-bound by strong data-protection laws
to look after your information. We're not going to sell/rent/spam/stalk using any information you give us, as that is dishonest and dishonourable.
Ergo, there's no need for disposable emails, because we'll look after your info.
