www.photoshopuser.com - invaluable resource for I think $100 yr. Online tuts (by the hundreds - from beginner to expert), a subscription to Photoshop User Magazine, and forums galore.

They have seminars all throughout the year that go to pretty much every major city, and they're tailored to different aspects, from very general (color corrections done right to presentation and finishing, to printing) to very specific (i went to the one with Bert Monroy about using the Pen Tool which had completely mystified me)..

As far as "online learning" as in a "class" - that's a tough one which is why you're not getting many responses. Learning is either part of a whole course altogether ("design courses" teaching various softwares and techniques, and BTW, you'll also learn some Photoshop). What you've specifically asked for (demanded, it seems, by the all caps text) pretty much doesn't exist - a specific online course in JUST Photoshop, that is. You'll usually find things like a "drawing" course, or a "design" course, etc., and one of the tools you'll use will be Photoshop, but it's not about Photoshop all by itself.

The next best thing might be www.lynda.com - you can buy training DVDs, as well as get monthly and yearly subscriptions for their online library. Again, this is not personal learning with you and an instructor - it's an online version of watching a training DVD.

www.thegnomonworkshop.com - another huge learning community that sells truckloads of training DVDs. I do believe they have some form of online "courses" (haven't looked into them, so I can't be specific), but their main thing is training DVDs. Pick your software of choice, and check out what they've got.

These next 2 might be what you're looking for as well as the Lynda site:

www.totaltraining.com - same thing. Look up your software of choice, and buy as many training DVDs as you can afford.

www.classondemand.net - same thing.

I hope this helps - good luck1
