ThePlaz.com is confirmed to work on the following browsers:
I recommend Firefox or Google Chrome.
I check IE6 to make sure basic functionality works. However, IE6 (now 8 years old) does not support advanced features like drop downs or transparent PNGs. In addition, it is really time to upgrade for security and usability purposes. I do not check versions of IE before 6. If you are running those, I can not guarantee anything.
If you are using versions of Windows before XP (2000, ME, 98, 95) than it is really time to buy a new computer.
I do try to make the site work in a text-only browser, though of course, this is not optimal for you.
