There is now an IRC channel on DALnet to chat about Melissa Joan Hart.
The channel is known as #mjh and can be accessed in several ways either via IRC Clients such as 'mIRC', 'WS-IRC', etc. or even via Telnet by going to "telnet.DAL.net".
Clients can be found all over the net but you could try "ftp.DAL.net/dalnet/clients".

The channel is fairly new and therefore not many people use the channel at present, but users are growing.
So if your a fan of Melissa Joan Hart, or of just Clarissa Explains It All, or Sabrina The Teenage Witch, then come along to #mjh.
More information on IRC and especially DALnet can bet found on the DALnet website "www.dal.net".

If there are any questions or suggestions about the channel, then mail me at the address below.
Also if theres a prefered time you would want to talk to other people in the channel then let me know, and I'll see if I can let other users know. Otherwise just pop along anytime :-)
