How can I install a 3rd-Party Web Part on my SharePoint 2.0 site

From mail2web.com Wiki

Because your Windows® SharePoint™ Services 2.0 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 Upload Web Part page under your Site Administration. 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.
