I tried registering for DesignSpark but they never sent me the verification email for my account. I tried two or three times, each time with a different email address, and they never sent it to me. I checked spam folders to make sure it wasn't filtered out, but there was not a single email anywhere from them. After the second or third try I gave up on them.
originally chose designspark due to its purported ability to import .dxf files from my solidworks cad software...
however there seems to be some glitches in activating downloaded software with newly registered accounts from my experience.
their customer support responded quickly to my initial difficulties,, we shall see if this goes well
