A friend of yours ($from_email$) has invited you to join the "$project_name$" project at http://aftok.com. Here's what you need to do to accept their invitation. At present, there's no user interface for the service other than bare HTTP requests with a JSON payload. A script has been provided below that you can edit to include your own information. You'll need to replace the following three tokens:

project at http://aftok.com. Here's what you need to do to accept their
invitation. At present, there's no user interface for the service other than
bare HTTP requests with a JSON payload. A couple of scripts have been provided
below that you can edit to include your own information. 
If you don't have an aftok.com account:
If you do not yet have an account on aftok.com, you can create a new account and
accept your invitation in one step. If you already have an aftok.com account that
you want to use, then then skip to the "For an existing account" section below.
To create a new account and accept the invitation, you'll need to replace
the following three tokens in the curl command below:

BTC_ADDR -- the bitcoin address that you want payouts to be initially sent to. You'll be able to change this later, but because changes of payout addresses are validated by checking transactions on the blockchain, it's important that this be a usable address that you control.

Substitute your own values for the tokens in the script below, then run it! Also, if you'd prefer that a different email address be associated with your account, change that as well.
