Also shooting what is demand will help as well:

So, choosing some of these briefs at random:
CelebrateFood2014 Brief issued Nov 2014. Files tagged: 1056. Files with dls: 35, mostly 1 dl. Only two with the tag for that brief have >10 dls.
NorthEurope2014 Brief issued: July 2014. Files: 3488. Files with dls: 194, mostly 1 dl. only two with >10 dls.
Femmeflux Brief issued: March 2014 Oooh, I got excited there, but wait ...Brief issued: Files: 6949. Wow, some files have >100 dls. But wait ... Ony one of those with >100 was shot in 2014. The others were uploaded in 2008 or 2011, and post-tagged. In the next row down, those with 30 - 50 dls, only one was shot in 2014, the others from as far back as 2007.
So anyone should think long and hard about responding to these briefs, if they have to make any sort of financial outlay.
(Of course, I haven't access to sales for Subs and PP. One of the problems with these briefs is that the requests might have been made by people on subs programmes, so they want expensive shoots for very little money.)
And for some reason, when clicking the 'Food loving' link, I
"do not have permissions to view this page." Wonder how many permissions one needs?
