Well, work is progressing on PerlMonks Editor. The first cut is available for download from CPAN at http://cpan.perl.org/authors/id/G/GR/GRANDPA/PMEdit/PMEdit-001.000104-1.pl. The next version will be available 'real soon now' and cleans up a bunch of rendering bugs and adds some of the features from the 'must have before release' list that didn't make the early alpha that is currently available.

Apart from that I have a template setup that includes my typical reply format - paragraph, code, "Prints:" paragraph and another code block followed by my sig. Since many of the posts I make include sample code, 70% of the time I don't need to add any markup. The another 20% of the time it's just delete the inappropriate markup, and for the rest I use PMEdit ;).

You can set up a template using Signature Settings.
