It's official, Experts Exchange have marked me as an expert after a couple of days answering questions. Now I'm able to ask the
hard questions that I've been trying to solve here at St Luke's.
I recall having an EE account earlier in their incarnation as a free service, but they must have shut down old accounts once the paid service came in. Not entirely sure whether it's a workable model with paid membership as it is competing with many other free sites, but the quality of answers is certainly there.
