Hello George,

I recommend using NoNumber ReReplacer to perform a Find & Replace of the author meta produced by Joomla.

Your search would look something like this...

Find:
<meta name="author" content="Old Name" />

Replace:
<meta name="author" content="New Name" />

I hope this helps,

Joe Campbell

thanks for the information joseph,

i read that it is not advisable to print out the author username and i think that it is right..so i preferred to hide the author meta tag throug glabal configuration.

but thanks again! :)

If he/ she is a Super User it is a major security issue.

Correct, that is why I recommended the replacement of it.

The "new" meta author can be whatever you want it to be, such as your organization name.

the author every time is different. it depends to whom the k2 item belongs. otherwise, authors are all registered users who can post stories. so i cannot replace with the nonumber extension to a specific value.

See if this helps...
