where to post requirements to split an author

author/hofmannmichael http://www.librarything.com/author/hofmannmichael should be splitted. See:
#1 LoC http://catalog.loc.gov/cgi-bin/Pwebrecon.cgi?db=local&Search_Arg=Hofmann%2C+...
#2 Hoffman (disambiguation) http://en.wikipedia.org/wiki/Michael_Hoffman_%28disambiguation%29

This is a multi hour work. Where to post such requests? How these will be coordinated? (It does not make sense that more people start working and revert each others work.)

Probably there should be added also distinct Common Knowledge Links .

Start splitting. People are generally good about not trampling on other's work -- if it's a massive project, you can ask for help on Combiners, but you needn't worry that others will maliciously or cluelessly revert your work.
