TWAMWIR stands for Tyne & Wear Archives & Museums Wikimedian in Residence. The identity was created by existing Wikipedia user Robertforsythe on 3rd April 2013. During March 2013 he had been appointed funded by Wikimedia to this three month residency. Hitherto contributions from the service have been signed TWASarchives. During the residency a number of new accounts will be created with links provided here and a number of alterations and new pages made. In case of any question the appointment is as Wikimedian in Residence, just a letter different from Wikipedian in Residence. This stresses his role in advocacy for all the Wikimedia projects.
