Is there a way to post without a fee to newsgroups?

This request is in respect of support for 20 year old DEC computer software and hardware, specifically for running RT-11 on PDP-11 hardware. So I hope it can be considered to be on topic I am using a newsgroups server that allows free read only access, but once or twice a year, I would like to reply. The newsgroups that are moderated allow me to send an e-mail directly to the moderator who then posts the e-mail to that newsgroup. I would like to post to vmsnet.pdp-11 and alt.sys.pdp11 - can anyone suggest a server that is available? By the way, I only use Netscape under Windows 98SE since other browsers don't seem to offer the same flexibility in saving incoming and outgoing e-mails. If either of these two newsgroups allow an e-mail to be sent to a moderator to then have that e-mail posted to the newsgroup, I would appreciate the e-mail address. I have heard that google allows posts to newsgroups, but the interface is so impossible to use as compared with Netscape that I have not even tried. Any suggestions would be appreciated!
