Email Templates

Hi.

I created an email template for Opportunities. See below:

Dear ${Opportunities.Opportunity Owner},

The stage in " ${Opportunities.Potential Name} " has been changed/modified to " ${Opportunities.Stage} " by ${Opportunities.Modified By}. This opportunity relates to the " ${Accounts.Account Name} " account.

Please review.

Thanks.

I had to add the last sentence mentioning the Account's name, because I cannot seem to be able to add the opportunity LINK. The only field available, apart from the opportunity name, is "opportunity ID", which is useless in this instance.

So my question is: How do I go about adding the hyperlink to the opportunity record, so the email's recipient just clicks it and is taken to the record s/he needs to review?

Thanks!!
