Just create an email address especially for Answerbank that doesn't have your actual name or any other personal details... [email protected] for example. Guess what I'm drinking right now!
You can always give them your actual email address after they've been properly vetted and decreed 'alright' by you... that's what I do anyway!
I've never had any rubbish from any trolls when I've put my adhoc email up... Not that I've done it in a while and actually I'd have to make a whole new one up now if I did want to. Can't remember the password :c(
Good on yer, Legs! That wee badly needed to be taken, and you took it with consummate elegance. Never give a we-er (or the I-ers &co) an even break. Say not the struggle naught availeth!
