Here is the revised text I used:
Your user name or IP address has been blocked by $1. The reason given is this:<br />''$2'' <br /> <br /> You may use the "email this user" feature to contact $1 or one of the other [[Project:Administrators|administrators]] to discuss the block. <br /> <br /> Note that you must log in and have a verified e-mail address to use the "email this user" feature. Creating an account and logging in are allowed even from this blocked ip address. If you didn't provide a valid e-mail address at the time of registration, you can add a valid email address in your [[Special:Preferences|user preferences]]. As soon as you respond to the verification e-mail message, you will be able to log in and e-mail an administrator. <br /> <br /> Your IP address is $3. Please include this address in any queries you make.
