Thank you for this constructive criticism. In my defense: I changed the date at least a week ago.

However, on Saturday someone brought to my attention that the dates in the summary-post of LW meetups by FrankAdamek and on the right side of the LW surface did not reflect this change, so I wrote to him about this problem. He probably changed the official date some hours later so you got the impression that I changed it on Saturday.

Generally, I thought that people would follow the link where they could see that the date was changed.

I apologize for any inconvenience this may have caused. Next time somebody with better organizing abilities should arrange the meetup. I hate organizing this kind of stuff and only did so because apparently nobody else was willing to set up something like this.
