I'm feeling a little dense at the moment.
I just can't get it to work, but I think it might be me this time.
I must not be putting in the path correctly or something.
Is the compojoomcomment4.1.7.stable.zip file the "package"?
I've tried the zipped file and the unzipped contents with the Install from Directory and the Install from URL options...just getting error messages: "Please enter the package directory", and similar.
Sorry...I'm showing my newbiness here. I'm goin to wait 'till I get home and try my home PC...maybe the 1st method will work. Argh!!
