Just a quick note for those of you who have posted your email addys here...unless it's a "throw away" address, you probably want to remove them from your posts. People do troll these boards looking for addresses.
You have 2 other, more private, options for getting your email to the OP. For either you need to click on the OP's user name on the left of his/her post. Then:
1) Choose "Send a Private Message to xxx" (user name)
2) Choose "Send email to xxx" - This option will only work if the OP has signed up to receive emails via the DIS. You will not see their email addy, but they will be able to see yours.
If you have fewer than 10 posts to the DIS you won't be able to send PMs until you've posted 10 times to various threads.
