I have the A.N.D.Haksar, Purohit Gopinath translations of all the Satakas and Swami Madhavananda's translation of the "Vairagya Shatakam". Need to get the others ;-)
Also i suggest that you add author names of all known translations of the work whether you have access to their actual text or not (due to copyright etc. reasons). That way your site can be a one-stop portal to Bhartrhari's Sataka-Trayam.
PS: In case you don't already know of it; there is a much larger work in the Tamil language named Tirukkural which is also divided into three similar categories (viz. Aram, Porul and Kamam) the whole having a total of 1330 couplets (133 chapters of 10 couplets each). There are many English translations available of which the original Penguin edition titled "Kural" translated by P.S.Sundaram is pretty good and done in the original couplet style. For a more detailed study see the 2-vol translation with commentary by S.M.Diaz.
