Reason WM9V's post is important.
From the ARRL Website:

Changes made three years ago to the federal tax laws could cause many radio clubs to lose their tax-exempt status this year. Clubs that are tax-exempt under Section 501(c) of the Internal Revenue Code must file the required IRS annual returns or reports before the deadline, which is May 15 for those with calendar years......
And so to my original statement. This list may be of interest to some--But very few. I would be surprised if this news found its way back to those clubs because of this listing. AND--this is about TWO states only! Far better if a letter was written to each of those clubs to advise them of this--at least they would see the letter!
