PR:
- Updated www.scitags.org with past and upcoming presentations
 - Question: I'd like to add logos of participating sites (UVic, UMich, UNL, KIT, CERN), please let me know if you agree (and/or if this needs prior authorisation and what would be the process)
- RNTWG update was presented at LHCOPN/LHCONE, HEPiX and FTS/XRootd workshop
- CHEP talk and paper
