I made a signature for everyone using the Frihost IRC channel. You can use it by putting this image in your signature:
http://www.bierkip.nl/frih/img/rvec/1/1/.png
example:

You can ofcourse replace rvec by your own username, the first 1 by 2 if you want the other skin (only 2 available atm)
and the last 1 by your timezone. The timezone only accepts full hours (not 5.5) and 0 = GMT.

You can also display the lest lines in the channel by all users. This can be done by using 'all' as the nick.
