Hi Rod,
Sorry I am not around on Wednesday, but happy to give some remote support before then.
One limitation you will probably hit is the number of Accounts that can be created on one IP address in one day. You can reduce that risk by having multiple IPs, by asking attendees to create an account in advance or by creating accounts for them. I would be happy to give either you or Andy the Account creator right if you want it, that isn't as newbie friendly as being able to create accounts themselves, but it bypasses that throttle.
The other throttles I can help with are that newbies are liable to face a capcha when they try to add links, and if you structure your workshop in such a way that you get to say "all hit enter now" you will find that six newbies successfully edit and the rest get their edit throttled. Both can be mitigated by setting participants as confirmed users - email me any user names you learn in advance and I can sort that out for you.
Exeter workshop this Weds 15th July
Hi all,
This Wednesday (15th July) I will be doing (with help from Andy Dingley) a workshop at the University of Exeter for web and comms staff from several universities – see https://wikimedia.org.uk/wiki/Exeter_University_July_2015 for details.
I will try to add to that page the usernames of participants and any articles edited during the day. If anyone had any time and could help to monitor, advise and guide the participants remotely that would be great.
Rod
