Since Penny & Aggie and Ménage à 3 are listed, you can as well add Gisèle Lagacé's latest creation, Eerie Cuties
, which has recently started. (There's also Cool Cat Studio
, this one is finished but still online. There's a few other completed webcomics listed there, so it wouldn't hurt I guess.)
Also, Metrophor is listed as Metaphor.
Also misspelling in Suicide for Hire.
The author of Yet Another Fantasy Gaming Comic also has Rich's Comixblog
which alternates between several comics (currently, "House of Paulus" and "Forever Janette", but there were others before, including some rare one-shot comics).
