Although I would try a cheaper alternative first, ballistic missiles might work.
Post Removal

How to remove my postings from my home page?
Which ones ?
Homepage notes?
tracked activities?
about me ?
new comments ?

Thanks for reply kohhai, if you look at my home page you will see three questions I have asked including this one and would like to remove all.

I think you mean your "recent activity" which links you to threads you've created in the forums. You don't delete those, they are part of the public forum, so that if someone else has a similar question they can read your thread instead of having to ask it again. (as if that ever happens...)

I don't mind them being available on the public forum I just want them removed from my home page and profile

Only staff can remove threads you make, but you can remove your own posts. The only way for them not to show on your homepage is if they are removed from the main forum
