Share issues as a phrase is, in a sense, is another way of saying work together. Issues can be problems, can refer to information (which can be exchanged as you said), or can be concerns or approaches to getting a job done. I am sure that this list could be expanded, but I think that this is the jist of what is being said.

The following is a similar use of the phrase from a chart in a UK website:

"relevant organisations
and community
representatives to
attend, where they can
share issues and work
to agreed objectives in
relation to New and
Developing"

THIS IS THE OTHER SECTION (about a joint working group and a joint model) FROM THE SAME WEBSITE, WHICH IS WHY I THINK IT IS RELEVANT (I forgot to add this section)

and therefore reflect to some extent different local priorities there should be an agreed joint
Strategic Framework based on:

! Neighbourhood Management, Community Development, and Partnership Principles
! The production of community agreed ‘local plans’ for the neighbourhoods focussed on
key issues
! The development of local Boards to manage the resource and direct the implementation
and monitoring of the plan
! A joint model for monitoring and evaluation
The Strategic Framework
The Strategic Framework is built on the following shared understandings:
Vision Statement (as earlier)
‘working in partnership with local people, service providers and decision-makers to
narrow the gap between the district average and less advantaged areas by improving
the life chances for residents in those areas in Huntingdonshire’.
