Hi! Wouldn't it be nice to add a [thank] button next to the [reply] button, to thank users for their messages? The relevant edit to thank could be found based on the timestamp. This would avoid clutter by unnecessary "Thank you" messages and would increase thank you notifications, thus spreading wikilove.
If this is not the best place to post it, or if it's been suggested already, I apologize and would appreciate a link to the relevant place. Cheers!
