Resign from ICAEW?

I bet the ICAEW website has some useful information and I'll mosey along there, but I'm interested in views from the folks on here - current members, ex-members, never-been-members.

My job, while notionally in finance, is more about maintaining accounting systems and much less about actual financial reporting or even book-keeping!  CPD is a joke - nothing I can learn from the available courses has any relevance to my work.  I get nothing of real value from my institute - not their fault.

My qualification wasn't even of much interest to my current employer when they offered me the job - as a demonstration of being able to attain such a qualification that's fine but they see little value in retaining it.  Of course if I change jobs then maybe I'll regret giving up my membership, although I think 5+ years not really being an accountant is more relevant than a qualification I earned 15 years ago.  When you've been working for 20 years surely experience counts for much more.

The other thing that worries me is how easy (or not) it is to resign.  I think I've seen accounts before of indifference from the ICAEW (typically when members resign complaining of the heavy compliance burden of being a small practicioner) but can't help wondering if I'll be bombarded with questions.

I don't take resignation lightly, and would welcome any thoughts...
