Have you ever donated to Wikipedia?

yes, more than once - and to other similar organisations.

Yes - I have donated more than once as I often use and find good, referenced information.

Yes I have too.

Yes because I'm always checking Wiki! It's a small price to pay.

Yes - donated for the second time last week £2.50.
I use it a lot - I think it's one of the best parts of the 'net - like a reference library.

Yes, I donated £10.40 a couple of weeks ago. As others have said, I use it several times a week and really value it. Whilst I realise that it can't be trusted on all things, it is a resource that I would certainly miss if it wasn't freely available.

Yes, I gave them £10 a few weeks ago. I too felt guilty that I often refer to it and shouldn't take it for granted.

Yes, a couple of times I've bunged them a tenner. I don't use it a huge amount but dh does. He's always disappearing down Wiki-rabbit holes!

Yes. I send them a fiver at least once a year.

DD for £2 a month.

Yes, every year.
