Hi!  Thanks for registering and for your offer of help.  As requested by Hu12 (a request which I completely agree with), we first must determine whether is support for adding the IUPHAR links at the appropriate Wiki Projects (WP:MCB and WP:PHARM). I will post a proposal and you are more than welcome to take part in the discussion.  If there is support for the proposal, it should be straight forward to (1) add an optional IUPHAR parameter to the GNF_protein_box template and (2) add the appropriate IUPHAR accession numbers to the appropriate Wikipedia protein articles.  Cheers.
