SharePoint Portal admins can manage and share personal content. SharePoint has a limit on the amount of disk space associated with each personal site; I think the default is set to 100MB. You can change this quota through the Administrative Tools (under 'Manage Quotas and Locks') but this will NOT impact any existing sites. Here is how you increase the site storage quota for an existing site:
1. Go to SharePoint Central Adminsitrator
2. Click Windows SharePoint Services
3. Click Manage Quotas and Locks
4. Click Manage site collection quotas and locks
5. Enter the URL for the specific personal site (e.g.http://in-srv-qaapp)
6. Click View Data
7. Under Site Quota Information, select Individual Quota under Current quota information
8. Change the site storage limit and click OK
