The donation "wellie" may suit some but I don't particularly like it as invariably at some point it will be put in front of me to donate.

I prefer to give by way of bank transfer straight into the WB bank account, that way you can give what you want in relative anonymity.
Having given in such a way, I don't want the "wellie" shoved under my nose and feel I'm not supporting the forum by not being seen to give to such a collection method
