Emptying the cache

Unison maintains two caches to speed up your Usenet browsing experience. The message cache contains message header information for groups you have accessed from Unison. The image cache contains copies of any images you have previewed from Unison.

To empty the caches, choose either "Empty Message Cache..." or "Empty Image Cache..." from the Unison menu. This may slow down your next visits to previously-visited groups, as the information will have to be downloaded again from the server.
