You can email the person who maintains the Struggle web pages at andrewnflood AT nospam.gmail.com
(The email address is the bits in red with a @ for the AT)

this is the best address to send translations or new material to as well as general enquiries about the site. Please make sure you have subject line that is clearly related to the site as I get a lot of spam at this account and vague subject lines may result in posts being deleted without being read.

For information on particular organisations with a site on Struggle you are much better off emailing them directly. Their email address should be on the top page listed off the Struggle index.
