I have got help from people on here a lot and often a reply solved the problem. I would like to thank these people but on the other hand don't want to post a one-liner (or one-word) post.
In my SMF I have installed the thanks-mod and it works fine so far. Wouldn't that be an idea for this board too?
The only problem with it is that it only allows thanks to the topic starter but maybe that can be changed so you can add thanks to every post you select?
