We heard back from Uncle Sam @ the IRS: MARCH is finally a federal 501(c)3 non-profit charity.
It took 9 years of prognosticating and 1 year of actual work. :) We needed to file using a different name than "Mid-Atlantic Retro Computing Hobbyists" so that's the other big piece of news here. Our charity's official name is: Wait for it ......... "Vintage Computer Federation". We'll continue to do business as MARCH. The new name, which happens to have the abbreviation "VCF" (get it? -- and yes we got permission from Sellam and from Erik K.), allows us to potentially expand beyond just being a regional computer club. Stay tuned for more announcements about this. :)
