www.reimnigh.com - an Irish verb conjugator.
I recently came across this site in my travels. It allows you to select which dialect you want to use and provides a conjugation table for selected verbs that is typical of the usage in that dialect (while acknowledging that there can be variation even within a particular dialect).
It only provides a small selection of verbs, because, for the most part, regular verbs are pretty regular, so it's mainly the irregular verbs, and some that may be handled differently in certain dialects.
(From réimnigh - "arrange in order", "conjugate")
