For the record, selling t-shirts and coffee mugs is exactly what we SHOULD BE DOING. Links to Amazon for books? Just the few pennies from the Arthwollipot annual book budget would probably pay for the servers for a month.
Those sorts of things can be done unobtrusively on a "Shop" page. And t-shirts, posters, coffee mugs and such are points of pride for some members. Of course, that's after we come up with a name and logo....
Icerat,
Do we have an estimate of hard figures? Just an estimate. How much are we talking about needing to raise annually to sustain the forums at breakeven plus one Euro? Are you aware of the potential angels and how much they might provide? Has this been discussed? If you were to poll the members, I'm guessing 75% would vote for "Donations and No Ads" and that half of those 75% would commit to an annual donation. (The same crew would refuse to pay a membership fee just because.... it's what we are, a bunch of contrary folks.)
