"If you are using the cache feature, clear cached files periodically by updating the general preferences in "system admin" => "preferences" for better performance."
This has been on the front page of XOOPS for while now. Seems to me that it could be made an option in admin, ie
Clear Cache every [5][10][30] days... Get rid of one more manual task for the webmaster?
Regarding this, a nice addition to the news module, would be to be able to specify Categories that are NOT displayed on the front page, or the category list, or the recent news...
Then you could use those categories separately, almost as a new module....
