I've found CS2 to work with Wine. Wasn't there a story of Google contributing code to Wine to make Photoshop work? CS5 is listed as Gold on http://appdb.winehq.org/objectManager.php?sClass=application...

I use The Gimp anyway (I know, I know).

Actually, browsing that entry paints a bleaker picture. Of the five most recent testing reports, two are gold, one silver, one bronze, one garbage.

According to the bronze report:

The text tool causes the entire application to freeze (even with atmlib installed). The paintbrush works only very intermittently. Moving and docking panels was buggy, and the bluish docking indicators instead rendered as black rectangles making it impossible to see.

and:

What was not tested: Vector manipulations, filters, adjustment layers.

It's fine for playing with Photoshop on Linux a bit, but not something you'd want to rely on for your business. I guess a virtual machine with Windows is still the most viable solution.

I tried Gimp. I really tried because I really wanted that to work... but just couldn't get out of Photoshop "mode" even after a couple months of using it. More power to you for succeeding!

I'm in Douala, Cameroon... So, when's the Africa HN Meetup? ;)

Big continent.... :-)

I still think you should validate, but instead of rejecting "incorrect" email adresses, just ask the user to check if there's no mistake.
