When we modify the Assigned To field in a Task list to allow multiple selections, the Task list will send out task assignment alert email to random emails whenever the task item changes. This is a known issue with WSS 3.0/MOSS 2007. More information can be found here.
Remote BLOB Storage (RBS) is an add-on feature pack for Microsoft SQL Server 2008. RBS is designed to move the storage of binary large objects (BLOBs) from database servers to commodity storage solutions. If the content databases in Microsoft SharePoint Server 2010 are 4 gigabytes (GB) or larger, consider using RBS as part of your data storage solution.

While administering our MOSS 2oo7 farm with many site collections which use separate content databases for each site collection, we noticed that the profile pictures are not getting updated inside the site collections (in discussion threads and other places where it shows user thumbnail, it shows users’ old picture) when the user changes it through his My Site.
The problem was because, we made the content databases offline after creating the site collection just to prevent another site collection being created in the same content database. So, in order to the profile sync between My Site and other site collections to happen, we need to leave the content databases in “ready” state. Still, if we want to prevent other site collections being created in the same content databases, we can make the maximum number of sites equal to the current number of site collection in the content database.
