What I found is:
- FAB6 2010 Amsterdam conference participants list (188) names, emails and affiliations;
- in my archive of 2012 I found a mindmap I made based on data of the fab lab global network composed by Ton Zijlstra (NL), I guess the data is from 2010 as Peru (2011) has not been included yet
- from 2010 - 2014 there were at least three mechanisms for registration, 1) Neil’s personal notebook, 2) Sherry’s annual list used for inviting for conferences, and 3) the Iceland Wiki (still online) for self registration and self assessment; if I remember correctly, the Iceland Wiki was an initiative of Frosti Gislaison, the list by Amy Sun and especially the self-assessment by Peter troxler;
- at one moment i had a copy of the three lists and analysed them for differences and to think about merging them; there were major differences; the iceland wiki was most complete and accurate; as it still is online, you can reversed engineer it; i do not know whether i can find these three copies and my analysis
- 18-8-2011 I made a print of the Iceland wiki list of that day.
- from FAB7 2011 Peru until FAB8 2012 Wellington the International Fab Lab Association was active; we published a newsletter every month with some statistics from the iceland wiki list; i have an overview from month to month (during only one year) as a graph
- FAB10 1014 Barcelona was the launch of the fablabs.io list
Some of this information I published today in Telegram HTPAA group.
