Help requested re my website

Hi, I'm hoping someone might be able to help me out. I work for an online website called www.lastingtribute.co.uk. It's a memorial site that allows people to leave messages for friends and family who have passed away.

I'm trying to find out how best to let ex-pats know but feel a bit naughty just going into forums and leaving a link to the site.

Can anyone suggest a way of targeting Brits in Spain, or do you think it's alright just to leave a link to the site?

Any help would be appreciated.

Thanks
