I don't have any knowledge of IiME, but looking at the public documents, IiME is a charitable trust established in 2006, and IiMER is a Charitable Incorporated Organisation (CIO) with identical charitable objectives established in 2013, the year that CIOs were introduced.I took a look at the financials for Invest in ME and Invest in ME Research. I don't know why there are two charities....
