Don't do anything irrevocable though. The gmane interface is not so great.
You have to confirm that you are posting on every post. I.e. post, receive e-mail with a link, click on link (or reply) and your post is submitted to gmane.
Then there is sometimes a second step where some postings from gmane have to be approved for the mailing list and this doesn't necessarily happen soon, or at all.
Or, you could just use a newsreader, which, presumably, is what the OP was after -- gmane.* groups. It's an e-mail => nntp gateway, the web interface isn't really necessary at all.
The approval stuff is at the mercy of the list admin for the list.
