I tried to do it - but it wants my bank details and access to my debit card at some later date.
I can't and won't get involved with that sort of thing.
I don't like putting my info on the net, I don't like big organisations getting hold of my details, I don't like sums of money disappearing when I'm not looking. I like it to go out of my account when I say so and when I actually do it. That way, I can make sure there is money in the account to cover it and I know how much is left. Even £5 one way or the other could get me in a mess and ending up with charges.
And I don't get inunndated with begging emails for more support for other projects I have no interest in, afterwards.
Sorry, I'd like to support it, but can't.
