It would be useful to list project contributors on the login page of the warehouse.
On the home page, the welcome message duplicates what you must already know. So some sort of dashboard and/or quick links panel would be much more useful.
It might be difficult to decide what entails being a "contributor" as nearly every project has helped improve the code a bit. As a start we could have:
HLF (via OPAL)
NERC CEH
JNCC
MNHNL (Luxembourg NHM)
