For XOOPS 2.0.x, in module System: Comment Manger:
Is it possible to have like kind of preview, and select several comments for action (such as active, pending, hidden, delete etc...)
a note of caution:
Fancy AJAX features may prevent google from being able to read and therefore index the content of your page.
If traditionally on your site you have a lot of keyword rich comments you may want these readable to google.
I have been concentrating on a Graphing Factory for XOOPS so we can finally have our live stats.
