#6 is the only entry by anyone so far that incorporates the concept I wanted. I like the little keyhole in the "a". I also like the stacked subtitle. Makes it pop more than the horizontal versions that other created. You have the start of something there, but it is not quite there yet.
Thanks for these. I need to think about which I like best. I think #36 is closest. Please see my latest update to the brief. If will give you a bit more insight into what I would like.
I think I like #47 the best. The caps look cleaner than the lower case letters. But after looking at them again, there are aspects of #6 that I also like. I need to reflect on which ones will work best. Thanks!
