While almost any template designed for 1.0.X will run on Joomla if you enable the legacy mode plugin, now that the release candidate has arrived, we will be converted some of our templates to run on 1.5 natively, withour legacy mode enabled.
We want you input on which of our Joomla templates you would like to see upgraded. Head on over to the Joomlashack forum and vote for your choices now!
