How can I install a 3rd-Party Web Part on my SharePoint 3.0 site
From mail2web.com Wiki
Because your Windows® SharePoint™ Services 3.0 site is hosted on a shared hosting platform, we may or may not be able to support some 3rd-party web parts.
Some Web Parts include only a single .DWP file and you can add them to your site easily from the Web Part Gallery. However, some web parts have additional installation files and must be installed by a Server Administrator. In such cases, you will need to contact support@mail2web.com to request installation of the web part.
Please note that our decision on whether to install 3rd-part web parts will depend on a number of factors including security, stability, and licensing. We are only able to install a web part if it is licensed for use by multiple site-collections on a single shared hosting server. We cannot install any web part which is licensed for use by a single user or single site collection only, as we have no way of restricting using of the web part to other customers on the shared hosting server.
