Now it would surely be manpower, given we are just 4-5 developers in total, often not all present for some time due to personal work/life commitments. So I think that for the time being, TDE will remain on TQt3, unless Tim comes around and has other ideas about it (given that he is the project coordinator after all). Cheers Michele
