There are a lot of materials posted in Books, Codes, Theses, Journals & Papers Request section as answers. Those materials, and they are a lot, should be inserted in their section. Also, a button would be good to show that those requests are solved.
@andersen3 :
hello
sorry for delay in my answer.
according to our rules if a user wants to answer a request, he/she shall post on true section, not in request section.
really it is hard for moderators to find answered topic and move them.
We discuss this topic in the past.
I'm still thinking that we need to create some kind of incentive to post in the right way.
If the member post a full answer as a new post, using the PostGenerator, could be considerate as point (to add in others considerations) as promotion for VIP member, for EXAMPLE.
In other hand, keep members doing short and direct answers (and don't punish them) it's necessary because it's a important material in the forum...
Creating a incentive to stimulate to do the right, encouraging, I think is the better way.
