You can not us Photoshop extension filters with PSP they have to be converted before they can work. Which can be a major pain in the butt. But yes you can mix or match em, you just have to convert them first.... Now let's say I combined them and put them under one forum. I think when people shared the filters with people we would have the same confusion that we get with P3 figures and P4 figures, where many P3 users spent time downloading it only to find out it wouldn't work. Couple that with people who have to pay by minute to be online (say UK for example) who download 6 megs of PS filters on a 56k modem and find out the 10 minutes they just spent downloading was for nothing, then spend 2 days shouting "why doesn't it work?" and get even more upset because now they have to download a 5 meg coverter. All because the person who uploaded the file never stated what program it was used for. That is what I aim to avoid and why I made seperate forums for PSP and PS. Jack
