This is possible, but it's perhaps not really in line with the reason off-topic forums were separated from the on-topic ones. That was done to put the focus of the site, and the information here, squarely on hammocks. The moving of threads is done to keep things organized to that end, rather than to encourage someone to donate.
The mods have always felt that wanting to support the site and its hammock information is the reason to donate. The off-topic forums are just a nice benefit.
“I think that when the lies are all told and forgot the truth will be there yet. It dont move about from place to place and it dont change from time to time. You cant corrupt it any more than you can salt salt.” - Cormac McCarthy
