I discovered tagging way back when I first got to MSN Groups. I would visit the PSP groups and would admire the tags they were making. I knew it was something that I wanted to do, so I took a look at a PSP Tutorial and I was completely intimidated, so I put off buying the software. But my hubby kept hearing me talk about how much I wanted to learn, so he would prod me to buy it, but I would tell him I'm not ready. One day he surprised me by buying it for me, and the rest is history (as they say). That was way back in 2005.
I also love to work with Animation Shop and nearly every tag that I make is animated. In fact my first tag was an animated tag and quite complicated, but it was a tag that I had my eye on as I am also a total hoarder of smileys and this was an animated smiley tag that I wanted to make so bad. It probably took me at least three hours to make it but I finally did and I was so pleased with myself haha.
I have also dabbled a bit with Ulead Gif Animator 5 but not too much. I love the effects you can create with it and one day I will have to re-install it and take another look.
I have heard some positive things about Photoshop, but I have never used it. Sometimes I will try to adapt a Photoshop Tutorial into PSP. If you've ever tried that, then you know it's not always easy or possible.
I am still using PSP8, my first ever version, and I have never thought to upgrade, so I know nothing of any other versions.
As to hosting a challenge, there's no pressure to do that; I just wanted to let you know it's an option in case you were ever interested. My group isn't like most PSP groups where the "manager" posts all the challenges. This group is mainly for hosting my PSP Tutorials and also a place to share tips and learn about PSP, so everyone is encouraged to do both. Feel free to jump in whenever you like.
