 Since mid-April 2021, many `#tor-*` channels are bridged (or
 "[plumbed](https://matrix.org/bridges/)") between the [OFTC IRC network](https://oftc.net) and the
 [Matrix.org](https://matrix.org/) home server. This is still somewhat of an experimental
-status, but so far it seems to be working well.

-By default, you will appear on IRC as a user like "YourMatrixName \[m\]".
-You can override this by sending `!nick <yournick>` to "OFTC IRC Bridge
-status". If your nick is registered, you will get a PM from NickServ stating

 Also note that you can join *any* channel on bridged IRC networks (Freenode and
 OFTC) through the [Portal rooms](https://matrix.org/bridges/) functionality.
-For example, `#freenode_#channelname:matrix.org` corresponds to `#channelname`
