Sorry guys, but I agree with rizla01 on this one.
This site attracts people with a wide range of computer experience and I think they all deserve the opportunity to submit comments and have their opinions considered. For many, this may be the first time they have ever attempted to download any software, let alone, tried to communicate with people far more experienced. For some, they may not even have learned how to 'copy' and 'paste' yet.
After they have taken the time to write out what they want to say and made the decision to submit it, to have the whole thing disappear because they didn't fill out a form correctly, or (and I'm sure many of us have found this out the hard way!) hit the 'forward' or 'back' arrow to check on something in the middle of a reply, may discourage them from ever trying again.
Is that the kind of site we want this to be, where newcomers attempts to participate in a discussion or ask for help are deleted due to inexperience with the submission process? Or is it a place where people can ask for help and have their questions answered, where 'newbies' are supported and encouraged to participate, where everyone's contribution is welcomed?
IMO the 'activating' and 'installing' procedures here are enough "wacky hurdles" to subject people to - why not simplify the procedure for posting comments so everyone can participate easily?
