I hope most of you are using Pidgin IM for chat. Till (Mar/19/2010) Pidgin latest version 2.6.6 is not available for Fedora 8 release. I have created the pidgin and libpurple rpm packages for Fedora 8 (i386) based on their source rpm.
Link for download:
Create a local repository and update the pidgin using YUM or install directly via RPM.
