The new Legacy/Mobile board setting allows me to make moves on my Palm T|X. Bravo Russ! I hope that analysis features are implemented at some point, but this is better than not being able to submit moves at all. Thanks!
It is a bit tedious, however, to keep switching from Legacy/Mobile to Modern (and back) and changing board sizes when moving from my computer to my pda. I wish there was a quicker way to do this - such as using cookies, or having user saved board setting presets that can be selected directly from the game page, or a seperate RHP url that utilizes a user's alternate board options.
