The second annual Gall Week is coming up, and it's going to be a little earlier in the season this time around: Saturday, September 3rd to Sunday, September 11th. To participate, just join this project, find as many different galls as you can during that time window, and add each observation to the project.
If you have any questions or comments about Gall Week, please post them here.
Thanks to @merav for getting this going!

@merav has declared the first week of October to be Gall Week! For details, see her post here.

I confess I have been completely ignoring this project in favor of leafminers, but I wanted to point out this great post on goldenrod galls by @ddennism:
