Yeah, we seem to be having a little problem with basic forum functions. It isn't possible to reply either (unless you use the Quote function and then remove the quote itself).
It's currently being looked into, so bear with us.
Could you try to remove the poll? (just to see if it's possible, and to tidy up the thread, of course). The "Remove poll" option should be just above the advertisements at the bottom, and theoretically it should work.
It doesn't seem to have that option, its just got 'Remove Topic | Lock topic'
I went into 'Edit Poll' but it doesn't seem to have anything in there either. Maybe delete the thread and we'll just post another one now that its working.
As for the widget thing : you could try searching for "widget" on the market, or adding widget to your initial search term. That may get you some results, although it may also list apps where commenters complained about the app not having a widget.
Personally I'm not really into apps. I downloaded only 7 or 8 apps, and none of them have a widget function. So I'm afraid I can't really help you there.
EDIT : problem with the forum has been solved. As for the poll, I'd still like you to try to remove it.
Thats a pity but i'll keep looking. If i find anything i post it up.
