I think your ideas are great. The old saying goes...

Nothing tried, nothing gained

I don't see anything wrong with submitting a proposal to SPS (Steem Proposal System). What is the worst that could happen, they say no?

Last I checked there were only two dozen proposals of which I have voted to support 4 of them. I would definitely vote for your proposal as it would definitely be a boon to STEEM in the area of marketing.

This is an area only focused on by a few influential people, for example @theycallmedan. Yes I went there and tagged him, hopefully to get his eyeballs on this great idea. It is definitely something I am sure he would be very interested in further investigating given his marketing activities of STEEM.

Charity? Why sure! Having received a great deal of help in the past when I was a homeless Vet, I am all about voluntarism. So much has been accomplished over the years by your Dollar-A-Day initiative and many other noteworthy charities on the Blockchain and also those currently still operating.

Getting a team together? Now that may be the hardest part. Hopefully, folks will wish to help.

I look forward to hopefully seeing all these initiatives coming to fruition!
