[Talk-gb-westmidlands] Personal Survey Points

[Andrew Mackenzie]

Hi Jonathan and everyone
I think we will have a chance for Mappers' Question Time at Mapitude, so people should bring questions like this. Bring your GPS as well, if you like. There will be people there who have not tried surveying who might want to have a go.
I have capped the ticket sales at 40 and there are 11 left at the moment.
