You can de-active displaying your own nick in your chat client.. This would just replace
<FunChatter> blabla
with
> blabla
To do this... goto to options window... ALT+O and goto IRC menu... uncheck the Prefix own messages box...
For the time... You need to de-active the timestamps thingy... Go to options window againn... ALT+O and goto IRC menu and under IRC menu find Messages submenu... in there, uncheck the Timesptap events box at the top of the window
