[HOT] Analysis of when mappers joined OSM

[Janet Chapman]

Does anyone know how to analyse when mappers in a particular project(s) joined OSM?  We're interested in analysing what proportion of mappers on these projects are new to OSM http://tasks.hotosm.org/?direction=asc&page=1&search=Tanzania+Development+Trust&sort_by=priority


Any advice appreciated, thanks.
