For something a little more customisable, check out the form designer by Interactivewebs on snowcovered or here on the dotenetnuke marketplace. That offers a simple way of creating a custom form. There are also quite a few, more complicated form designers if you needed more... xmod, h2o... look in the forms section on Snowcovered. Also... depending on exactly what you're doing, you may prefer a bookable events module. Look at Smart Thinker's Events and also do a search on snowcovered or the Markletplace here. There are a few.
