The above question headed a Guardian article on September 9th 2008 and I'm very sorry I didn't tell you about it at the time. If you want to keep teaching in adult education you need to keep at least a bit au fait with the (drastic) things happening in that sector. Spending, budgets et cetera... not very creative but it does affect us teachers of creativity.
That article announced the formation of the Campaigning Alliance for Lifelong Learning (Call), a banding together of bodies (stakeholders, if you use that kind of language) to lobby and pressure politicians re lifelong learning. It could be that U3A (University of the 3rd Age) is what/who we all come to rely on for providing what's called informal adult educaton.
If you are that way inclined, for an update see http://www.callcampaign.org.uk/
For a more recent Guardian article on further education for older adults, see http://www.guardian.co.uk/education/2009/jan/20/furthereducation-longtermcare
These nifty shortcuts to news-right-up-our-alley come to me via the Instititute for Learning http://www.ifl.ac.uk They send a quarterly e-newsletter with news digest links; IfL is also 'our' body for official registration as a teacher in further education.
Frankly (my dear) politicking is not my thing, so if you want even more directly writers-who-teach-creatively news and conferences etc don't forget the National Association for Writers in Education http://www.nawe.co.uk You can even list yourself on offer to go into schools etc. NAWE addresses creative writing teachers going into schools, universities and community (which includes further education).
End of commercial. I see my private writing coachee tomorrow. Next week I will be more creative, less administrative.
