To some questions asked there is an endless thread of answers some repeating what already has been said sometimes several times before and some just making a use- and sensless statement on their personal feelings "like very good question". When I ask a question I expect a peoper answer and after a time all is said what has too be said, but some threads seem to inhabit the features of an "undead". What about RG installs a key "End", where the questioner can terminate the tread if he/she is satisfied?
