Trying to find out something about Reader Extensions for Designer 7. I can't figure out (from the Adobe web site) how to obtain this product/software or what it costs (or if it's a free add-on). For those who will ask... I need to make a PDF form where the data can be saved. My understanding is that this functionality came with the CS3 and later (Acrobat 8+) versions (in Acrobat, under Advanced > Extend Features), but I can't find anything correlating to that in Acrobat Pro 7 or Designer 7. Thanks in advance.
