The Shirt announcement is a style of announcement that cannot be removed on a per-person basis. It's meant more to be like an "Ad". If people are finding it annoying we could remove it, though TBH it's not exactly in your face.
I added the blog and club activity feeds to see if it'd get people more actively interested in them. Maybe I move them elsewhere or something.
Eventually we're going to have a different "front page" which will amalgamate all the latest news and featured posts etc.. For now we're experimenting to see what works with what we've got, as that front page will require a bit more effort.
If you add a poll to this thread giving people the option to choose between keeping/getting rid of the Latest Blog and Latest Club feeds, I'll remove them if people vote that way.
