Foxit PDF Editor  Hard to understand how Adobe was so succesful in convincing so many governmnt agencies, educational instutions  & others to adopt .pdf.
		
 
		
	 
Not really - it's a very compact, flexible format; it's open to indexing, it's WYSIWYG, it's searchable, it's printable, has built in, efficient OCR.... I can continue with lots of reasons.
Foxit (and many others) is around because Adobe made the format ubiquitous by offering a free reader for years, and left the format available for others to build tools around. There's probably a license needed, but I'm doubtful it's very restrictive. As for being essentially uneditable, it's not meant for editing - it's meant to be portable... read freely by anyone anywhere; it was designed for the print industry to be able to send virtual proofs to people who needed to view them in high resolution without loading fonts or rasterizing everything. Acrobat is not an editing application. It's like being upset about how hard nails are to put into a board with a screwdriver - it's not the right tool for the job.
As for the OP's question, use the Forms tools. Their location varies depending on your version of Acrobat, but in 7.0 pro there's a pallette for them in Tools->Advanced Editing. Designer's also available (as a part of Acrobat Pro) but can be a couple degrees of overkill with a learning curve attached if you're not trying to do anything terribly complex.
Feel free to PM me if you like, I might be able to give you some additional guidance.
