I have a droid pad from sprint, i can use it to send email and type all kinds of other blogs, when i am on this site i do not get a keyboard pop up and cannot respond or post from the pad, i seem to be fine on other websites such as armslist, gunbroker, pinecam. I can post and reply just fine

I am posting this from my droid phone on the same system, what am i doing wrong on the pad?
