Hmm. Propogating over team sites - I don't think that you can do that, just as Craig says.
Youcould save your site with your modified page as a template (provided itisn't a publishing site), and then use that template for your newsites. I think that should work (I must try sometime!) but it won'taffect existing sites.
Alternatively... if your root site is asite with the publishing features enabled, and you've made this changeon a Publishing Page (as opposed to a normal team site page - the twoare quite different), then you could turn on the publishing features on all the subsites, and they use your newly modified page la yout/s. However, that means going through each site:
- turning on the publishing features,
- creating a new home page,
- and changing the site to point at the new one.
It doesn't save any effort, I think.
You could, in principle, change the original files on the disk in 12 HIVE, but:
- Anypages which have already been 'customized' will not be changed. Inother words, if I make certain changes to a page with something likeSharePoint Designer, SharePoint will take a copy of that page and storeit in the SQL server database. When someone requests the page, they'llget that copy from the database, rather than the original file from thedisk.
- Any changes to the files on disk would affect all team sites farm-wide.
- Files would need to be changed identically and simultaneously across all front-end web servers.
- I'm not quite sure how this would affect any support agreement with Microsoft.
Consequently, I'd strongly recommend
not doing that. Instead, make your changes manually for each site, or create a template and recreate all your team sites.
Eitherway, I highly recommend a little reading around the differences betweenpublishing pages and normal pages in SharePoint, and reading aboutcustomized vs uncustomized pages (irritatingly also calledunghosted/ghosted pages in SharePoint 2003)
EDIT: and yes, you can use the PlaceHolderLeftNavActions, but be careful what pages you do this for - it is used on some pages.
