Ya, the date was probably not the best idea, but you live and learn. I was just getting freaked out, as I'm sure the rest of us was, of you just becoming another one of those 'fly by night' coders that promises but never delivers.
However, as you said in your post, you have a great reputation, you've released many hacks, so I have no doubt in your abilities.
Take time to get your site up and running, and I hope to see your GRPS hack released soon, I am very anxious, its going to be a superb hack!
Oh... and you'll have to start using that other hand for counting donations, but I'll be sure to donate
*edit* Question for you... if I install your older 1.0 Beta 4 version now... because I am launching my site tomorrow... and so I need to have some sort of 'groups' feature... if I launch it with your older version, will you be releasing an 'upgrade' type patch of some sort that will easily let me convert all my existing group data from 1.0 beta 4 to the new version without errors or loss of data?
