Sometimes the community sends too many emails! For example, if you replied on the "Introduce yourself!" thread, you probably don't want to get an email for each additional response.
To limit the emails the community sends you:
I have 48 pages of subscriptions. Very hard to find a specific one.
You can also go into a thread, click on "Options" in the top right hand corner, and unsubscribe.
@PhilipDAth Had to do this today after the introduction thread seemed to blow up! I guess the community has been discovered by the masses now.
