This may make me seem a spoilsport, but please don't display emails publicly. Every single day we get spam bots coming into the forum and they will harvest emails and bombard you. We have a few public emails on the site that we have to display and I can't remember ever seeing my spam folder below the 2,000 messages level.
There's also a chance that you will be sending spam- they will know the email is active and spoof it to send out millions of viagra emails and you might find yourself unable to send emails. It really is in your interests not to do it. Also, things like (at) or removing the dots don't fool them either- they have every possible pattern of pat. Use private message or you can send emails from the person's profile or the Send message link on this page under the name. Click on the link and it'l bring up a box to send it. If there's no link, then the person has opted not to allow email, so try private message if you need to contact them.
Thanks a lot
