Happy downandlonely day

Every forum has a default view of how many of old posts it shows. For many forums it's a year, but for Kudos, it's only 2 months because that has traditionally been a busy, active forum with a lot of posts.

Remember, too, you can search only in specific forums. I clicked on "Search this forum" then typed in "downandlonely" and it popped right up as a result.

Glad I could be of assistance with understanding how forum views work, and how to use the "search this forum" functionality.
