Hi.

I have a link to register with a token in a plain text email file.

The link looks like this

[http://someurl/register?token=123456789](http://someurl/register?token=123456789)

However, the link in the email looks like this

[http://someurl/register?token=3D123456789](http://someurl/register?token=3D123456789) - there is an extra 3D in  
there  
for some reason…

The mailer function looks like this:

def invitation(invite,user)  
@subject = “#{user.login} invited you to join”  
link\_string = “[http://someurl.com/register?token=](http://someurl.com/register?token=)” +  
invite.register\_token.to\_s  
body :user =\> user, :invite =\> invite, :reg\_link =\> link\_string  
recipients invite.email  
from Settings.email\_form || “removed\_email\_address@domain.invalid”  
content\_type “text/plain”  
end

The line in the email is just \<%= @reg\_link %\> and the file is called  
invitation.text.plain.rhtml.

Will appreciate any feedback

Regards  
Ivor
