Item 1.  Security and Issuer

     This  statement  is filed  pursuant to Rule  13d-2(a)  with  respect to the
shares  of  common  stock,  $.007  par value  (the  "Common  Stock"),  of I-Link
Incorporated  (formerly Medcross,  Inc.), a Florida corporation (the "Issuer" or
"I-Link"),  beneficially  owned by the Reporting Persons  specified herein,  and
amends and  supplements  the Schedule 13D filed April 14, 1998,  Schedule  13D/A
(amendment no. 1) filed January 28, 1999, Schedule 13D/A (amendment no. 2) filed
October 20, 2000 and Schedule  13D/A  (amendment  no. 3) filed  November 1, 2000
(collectively, the "Schedule 13D"). Except as set forth herein, the Schedule 13D
is  unmodified.  Capitalized  terms used but not defined herein have the meaning
given in the Schedule 13D.

Item 4.  Purpose of the Transaction

         Item 4 is hereby  amended and  supplemented  by adding the following at
the end thereof:

         Red  Cube  failed  to make the  deliveries  required  of it  under  the
Securities  Purchase  Agreement at the First  Closing,  which was to occur on or
prior to December 31, 2000.  Winter Harbor has received  notice  pursuant to the
Securities Purchase Agreement that Red Cube submitted a request for mediation to
the American Arbitration Association on December 29, 2000 to resolve unspecified
disputes and controversies  between Red Cube and Winter Harbor arising under the
Securities  Purchase  Agreement.  Winter Harbor believes that any alleged claims
against  Winter Harbor under the Stock  Purchase  Agreement  are without  merit.
Winter Harbor intends to vigorously  enforce its rights,  including  seeking all
available legal remedies and damages.
