Hi. I run IRATA.ONLINE. Where should I post news? :) -Thom

[aleph_minus_one]

On the website, of course (ideally provide an RSS or Atom feed, too).

[stray]

On a gopher site!!! Maybe a dial-up BBS?

Realistically, on your own website. I've never used Facebook. Never will.

[tibbon]

As a .plan file on a finger service?

[huimang]

The site itself (it could be statically generated) with an RSS feed, a mailing list, and/or a matrix channel.

[detourdog]

Start a mailman List.

[mindcrime]

Usenet.

You can also just submit happenings like any other contributor here.

My chance to congratulate you on the site and work!
