I (tremble) am currently trying to get the various packages we use at work into EPEL, perl-Text-WikiFormat is one of these packages. While there is already an EL-5 branch for this package there do not appear to be any EPEL builds. Would it be possible for you to build perl-Text-WikiFormat and add it to EL-5 EPEL? I am willing to co-maintain the EL branch (and Fedora branches) if you would like.
