I am sure he would be able to help.
I have no doubt he would, but I get the impression that no-one asked him.
The situation of Simple Machines is more complicated. More expenses, more domain names, more stuff, more moving parts, more history.
More expenses: fair enough, though at the end of the day as far as the form is concerned it should be a total at the bottom of the balance sheet, as it would be for other companies.
More domain names: should be irrelevant. As far as I know, only two domains are held by SM NPO, but that's ultimately a justified organisational expense, and so goes into the above as another line on the balance sheet.
More stuff: certainly. The problem I'm having is that the more I look at it, the more I'm thinking 'more stuff to find excuses for'. This is the part that's an issue: for an organisation that swore it would have more transparency, it isn't doing a good job of this.
More moving parts: wouldn't have thought it would have made that much difference. At the end of the day, if there is a problem with filing the document, either it should be handed over to a suitably qualified accountant to arrange, or someone should be contacting the IRS for advice. Right now I get the impression, however accurately or not, that it's being sat on because it's 'too hard'.
