Entry #4 definitely has the "helpful" vibe, but it's more in a social outreach non-profit way (services for underprivileged), which is not what we are about.
#3 and #16 are drawing interest from our board members. Anything else you have along those lines or small tweaks of those would be of interest. Thanks.
Dear CH, thank you for the feedback. I have revised #3 and #16 by added some tweak as you suggested. Hope you like them. Feel free to comment or ask. Thank you.
