Some good web parts for free
"Every so often we develop tools or software bits that we may find either particularly useful or simply educational. Typically we are able to provide these downloads free of charge and anyone is free to utilize them (providing you accept and comply to any license agreement attached to them) for your use. We also will post here (more infrequently) whitepapers or presentations given by us in public forums. Please feel free to download these items for your use, and if you have feedback, we'd love to hear it. Please keep in mind that these tools are not our primary priority, so we apologize in advance for delay in version upgrades...but if enough people whine appropriately, we'll get it done"
