Putting aside the discussion of the merits of including a Tip of the Day in an application (a la Is Tip of the Day Good) I am seeking either a ready-to-go library or C# source code for a .NET tip-of-the-day dialog for an open-source project (so I am looking for an open-source component, of course). It is usually easy to locate a needed component with a direct search, but searching for "tip of the day" is an exception: most of the results, obviously, are tips rather than how to implement tips. ( It is akin to searching for help on a stack overflow problem and getting 99% of the results pointing to StackOverflow.com! :-)
I have found only one candidate thus far (Tip Of the Day Dialog). I prefer to have more than one candidate to be able to compare and contrast, and thus more readily determine the features one would want. Besides a general search, the only supplier of free components I am aware of is Devexpress but they do not have a tip component.

Just to address the point from JPMarichal: yes, it is easy enough to make a component like this, but it is still reinventing the wheel and I have a passion (obsession? :-) for finding existing building blocks. The more common/widespread something is, the more reason for there to be an off-the-shelf building block.
